Upgrade Your 2025 4Runner: Installing the Wolfbox G900 TriPro Bumper Camera

Do you own a 2025 Toyota 4Runner SR5 and want a top-notch digital mirror and dash camera? Many drivers look for ways to improve their vehicle's tech. Some start with cheaper cameras to save money. But these often fail quickly. A common issue is the screen getting dimmer until it no longer works, even if it still records. If you're tired of unreliable cameras, it's time for an upgrade.

This guide covers installing the Wolfbox G900 TriPro Bumper Edition into a 2025 Toyota 4Runner. The Wolfbox G900 TriPro offers a high-quality camera system that acts as an ultimate digital mirror. This install will make your camera look like it came right from the factory.

What's in the Wolfbox G900 TriPro Kit?

The Wolfbox G900 TriPro kit comes with many parts. These parts help with a smooth setup.

You get:

• The main camera unit.
• A GPS module.
• A front bumper camera.
• A rear bumper camera.
• A trim tool.
• License plate mounts.
• Zip ties.
• Small wire holders.
• An AC adapter.

Important Note: Make sure to get the hardwire kit if you do not use the Donggar Pro power adapter. The kit also includes rubber straps to fit the camera over your original mirror. However, for the Toyota 4Runner, the Model 190 OEM Style Arm is highly recommended. This arm helps your install look factory-made.

Choosing the Right Mount: Why the Model 190 Arm?

The Wolfbox G900 TriPro comes with an insert. This insert shows all features like the lens, fasteners, and ports. You will remove the original fasteners and rubber straps. These parts allow you to strap the camera over your existing mirror.

Instead, you use a replacement arm. Remove the small rubber pieces on the back of the camera. Underneath, you will find Phillips head screws. Use these to attach the back plate of the camera to the new arm.

The Model 190 OEM style bracket works well on Toyota vehicles like the Land Cruiser and 4Runner. It is better than other models, like the Model 1 often used in a Bronco. Toyota vehicles have large plastic covers behind the mirrors. If you use a Model 1, these covers would block too much of the camera's view. The Model 190 arm drops the camera down just enough to avoid this blockage.

You will reuse the four screws from the original mirror. You will also use four screws supplied with the 190 arm. The arm kit often provides five screws, just in case one gets lost. Keep all leftover parts, including the rubber straps. If you move the camera to a different vehicle later that does not have an OEM style mount, you can switch back to the universal setup.

Attach the arm to the base plate. Make sure it faces the correct way. The camera should be upright. It will then slide onto your windshield mount.

Adjusting Your Camera View with a Double Hinge

Wolfbox kits offer many accessories. One key feature is a double hinge. This double hinge helps you get the camera in the perfect spot. A single hinge only lets you adjust the camera in one way. The double hinge offers much more movement and control.

To add the double hinge, take off two screws from the single hinge. Then, remove the single hinge and screw on the double hinge. This extra hinge is especially helpful for the rear camera.

For the rear camera, you want it as close to the glass as possible. This prevents glare from inside the vehicle. It also helps avoid seeing the defroster lines on the glass. The double hinge lets you tuck the camera high up and close to the window without it hitting the rear hatch or glass.

In the 4Runner, when mounting the rear camera high, the windshield wiper blade might not reach that area. This can leave dirt or water on the glass. One idea is to use a glass treatment in that spot. This may help water move away from the camera's view. Mounting the camera on the outside is an option, but outside areas can also get dirty. Keeping it mounted high gives a good rear view. If it gets dirty, rolling the glass down and up can help clean the area with the rubber seal.

Rear Camera Mounting Details

The headliner has plastic fasteners holding it up. The acrylic rear camera mounting plate from StickerFab has a hole. This hole lets you push the fastener straight through the original hole. The plate also has adhesive to stick firmly to the headliner.

You can then screw in the double hinge. Wolfbox provides two small screws for this. Be careful not to lose them as they are tiny. An adhesive pad is also an option, but the screws offer a firmer hold.

Set the camera to the right angle. Then tighten the screws. Do not overtighten them, especially if using an acrylic plate, as it can strip. You might not know the final camera position until the main camera is fully installed and turned on. Then you can make final adjustments for straightness.

Route the cable to the side and tuck it behind the mount. This helps keep it from being pulled out. For this installation, the wire runs down the passenger side and up to the camera.

Removing Your Old Mirror and Setting Up the New One

You need to access the area behind your original mirror. This is true whether you use an OEM style adapter or strap the new mirror over the old one. You need to route wires through the center.

To remove the plastic cover behind the mirror, slide it down the windshield. Do not pull it straight out. Apply pressure and push down on both sides. To remove the small center portion, pull it towards you.

You need a Torx screwdriver to remove the OEM arm. The new aftermarket arm uses a Phillips screwdriver. The mirrors simply pull up from the mount. Then, you install the new mirror over the OEM mount. Tighten the Phillips screw.

The OEM style replacement arm places the camera so your sun visor can still be used without hitting the mirror.

Powering Your Wolfbox Camera: Hardwire Kit vs. Donggar Pro

The Wolfbox hardwire kit provides power to the camera. It comes with many different add-a-fuse types. These are universal, so your car will likely use one of them. Add-a-fuses protect your car's original fuses. If the camera system has a short circuit, the add-a-fuse will blow, protecting your car's electrical system. The most common cause of a short is wires rubbing against trim and wearing through their insulation.

In the 2025 4Runner (and 2024+ Tacoma), fuses are under the glove box. You push clips to drop the panel down. However, add-a-fuses can make it hard to put the cover back on. You would use an accessory power fuse and a 12V constant fuse. Then, you run wires up behind the dashboard, through the pillar, and to the camera.

The Donggar Pro Advantage

Modern Toyotas often have an OEM dash camera option. Because of this, they have a five-pin harness that provides ground, constant, and accessory power. This harness is under the glove box, tucked behind a carpeted area. Pull it straight down from the back, not the front. Pulling from the front can break the tabs.

The harness has three wires:

• Ground wire: This wire is a little lower than the others and about one pin from the outer edge.
• Constant power: This wire is on the very outer edge, next to another wire. It is often red.
• Accessory power: This wire is in the middle of the other two.

You can cut off the hardwire kit's add-a-fuses, strip the wires, and use posit taps to connect to these wires. If the wires are hard to reach, pigtails that plug into the harness could be an option. You could solder these to your wires or use posit taps on them.

For this installation, the Dongar Pro is used. It's a plug-and-play solution from Dongar Technologies. It has a five-pin harness that uses three wires. You simply plug it in, connect it to the Wolfbox, and you're good to go. You can find the Dongar Pro at StickerFab or Amazon.

The Dongar Pro provides constant power to the mirror. This allows for different parking modes:

• Ignition mode: The camera turns on and off with your car.
• Infinity mode: Records until the battery drops to 11.8 volts. This keeps recording as long as possible but can drain your battery over time.
• 4-hour mode: Records for up to 4 hours after the car turns off. It still has low voltage protection. If the battery hits 11.8 volts before 4 hours, it will cut off. This is a good balance for gym trips or grocery runs.

The Donggar Pro uses a USBC port. You will need a USBC to USBC cable to connect it to the G900 Pro. Hide any extra wire behind the mirror.

Routing Cables for GPS and Rear Camera

With power set up, route the other wires. The GPS module should sit on the dash, pointing to the sky, for best signal. Run its wire up the A-pillar and over to the main camera.

When tucking the cable behind the A-pillar trim, if wires don't go deep enough, you can remove the caps from the handle. Use a 10mm or 12mm socket to take out the bolts. This lets you pull the plastic trim down. Then you can stuff the wires out of sight.

The rear camera wire uses a USBC connector for the camera. It also has a wire for reverse lines. If your 4Runner already has reverse lines in its OEM backup camera, you don't need to connect this. Otherwise, connect it to the reverse signal wire (the one that powers your reverse lights). This will show lines on your camera when you reverse. The rear camera wire is very long, so untangle it first.

Route the GPS and rear camera wires up behind the mirror mount. Bring them out through a hole in the trim piece. Plug the rear camera into its USBC port on the main camera. The GPS plug is right next to it.

Running the Rear Camera Wire Through the Cabin

To run the rear camera wire along the top of the vehicle, pull down the rubber door seals. This allows you to tuck the wire behind the headliner. Pull the A-pillar back slightly to push the wire through to the other side.

Next, run the wire behind the B-pillar, pulling it straight to the back. Tuck the wire behind the headliner. Later, put the rubber trim back into place.

Near the rear hatch, pull the trim back with a few quick jerks. Be careful not to lose any fasteners. Connect the rear camera. You can turn on the system to check the signal. Then, run the wire up and through the headliner, tucking any extra wire there. Avoid stuffing it near the seatbelt, as it can get tangled.

Pull the headliner down a bit. Give the rear panel a quick jolt. Run the wire behind the headliner, down into the gap, and out the front of the trim. Then, tuck it into the window trim. Use the supplied trim tool to push wires deeper if they show. Continue tucking it behind the S-pillar and gather any extra wire there. Pop the trim back in.

Bunch up any extra wire neatly by running strands back and forth in loops. Stuff it into the headliner. Make sure the rear camera signal works once everything is connected. The camera takes a few seconds to boot up. Once confirmed, push the rubber seals back into place, covering the headliner.

Installing the Front Bumper Camera

The Wolfbox G900 TriPro uses a Sarvis 2 Sony sensor. This is an upgrade from older G900 models, offering better picture quality. The front bumper camera is a key feature.

Mount the front camera high on the bumper, rather than in a lower, dirtier area. This location is similar to where some stock cameras are found on other vehicles. The camera can be flipped digitally inside the cabin if needed.

The camera can be mounted using screws or with 3M adhesive tape. If using the 3M tape, make sure the temperature is above 55 degrees Fahrenheit for at least 72 hours for a strong bond. Clean the area before mounting. Move the camera as far forward as possible to avoid the bumper blocking the view. Center it and push down hard to secure the 3M adhesive. The camera will register on the G900 display once plugged in.

Wolfbox cameras allow you to adjust the view up and down for all cameras. The rear camera also has a zoom feature. Set the view to see as much as possible, both far down and far up. The main front-facing camera will capture the rest.

Running the Front Camera Wire

Running the front camera wire through the firewall might seem hard, but it's manageable. You need to route it through a rubber boot in the firewall. Make an incision on the top of the boot, slightly off-center to avoid the main wiring harness.

Use a wire hanger or a long screwdriver to push the wire through. Tape the camera wire to the tool. Then, push it through the boot.

Inside the cabin, on the driver's side, move the carpet back near the pedals. You will see the rubber gasket and the main harness. Pull the camera wire through into the cabin.

Route this wire up through the headliner, over to the A-pillar, and behind it. Remove the rubber door seal on the driver's side and run the wire all the way down. Tuck the wires inside the trim. Then pop the trim back into place.

Under the hood, remove the plastic panel by pushing down on the clips and pulling them out. Before reusing, reset the clips by pushing them through completely. Then place them in the hole and push them flat.

Route the camera wire along the front, avoiding horns, extra wiring, and active shutters. These shutters move, so keep the wire clear. There is often a hole near a grill tab where you can reach through the active shutters to grab the wire and keep it forward.

Connect the camera wire. Replace the panel cover. Bundle up any extra wire and secure it with zip ties.

Final Assembly and Settings

Tilt the mirror down. Gather all wires in the center. Reverse the removal process: push the mirror up against the windshield with even pressure on both sides until it clips into place.

Ensure there is enough slack in the cables for the trim piece. Slide the trim piece down, then push the top back. The Donggar Pro often comes with a small mounting bracket with 3M adhesive. Clip the module into it. Mount it in a spot where you can still access its settings tab.

Adjust your mirror, and you're all done with the physical installation.

Basic Camera Features and Settings

When the camera is off, you can use it as a normal mirror. If glare is an issue, matte screen protectors can reduce it. However, with a matte protector, it won't work as a normal mirror when off.

Basic camera functions are simple:

• Scroll left/right to cycle through camera views.
• Tap and slide your finger up/down on any camera view to adjust it.
• On the rear view, you can zoom in and out. It's best to keep it zoomed all the way out.

Important Tip: Vehicles in the camera mirror may appear farther away than they are. Always use your side view mirrors to judge distances accurately, especially when you first start using the digital mirror.

To access settings, tap the screen and select "settings." There are many options. One quick setting to adjust is daylight saving time to get the clock right. Other videos can guide you through settings like parking mode if you use a hardwire kit instead of the Dongar.

When setting up your rear camera, push it back as far as possible. Make sure it does not hit the liftgate. Being close to the glass prevents glare from inside the vehicle and reduces the visibility of defroster lines.
