Toyota 4Runner Dash Cam Adapter
Toyota 4Runner Dash Cam Adapter
The Toyota 4Runner is the ultimate overlanding and off-road SUV — and a dash cam is essential gear for trail documentation, trailhead security, and insurance protection. Whether you have the massively popular 5th gen (2019–2024) or the all-new 6th gen (2025+), there's a Dongar adapter that fits your 4Runner. Multiple connection points, trim-specific options, and the cleanest dash cam install you can get — no hardwiring, no fuse taps, no tools.
Which Adapter Fits Your 4Runner?
6th Gen 4Runner (2025+)
The all-new 6th gen 4Runner has up to three connection points depending on your trim. The DCA-5A domelight connector is standard on all trims and is the recommended starting point. The autodimming mirror is optional on most trims — if yours has it, you can run two Dongar adapters simultaneously.
| Trim | Mirror (DCA-10B) | Domelight (DCA-5A) | TSS 3.0 (DCA-16T) | PRO / PRO+ |
|---|---|---|---|---|
| TRD Pro | ✓ | ✓ | ✓ | ✓ (5A recommended) |
| Trailhunter | ✓ | ✓ | ✓ | ✓ (5A recommended) |
| TRD Off-Road | If equipped | ✓ | ✓ | ✓ (5A recommended) |
| TRD Off-Road Premium | ✓ | ✓ | ✓ | ✓ (5A recommended) |
| Limited | ✓ | ✓ | ✓ | ✓ (5A recommended) |
| Platinum | ✓ | ✓ | ✓ | ✓ (5A recommended) |
| SR5 | If equipped | ✓ | ✓ | ✓ (5A recommended) |
5th Gen 4Runner (2019–2024)
| Configuration | Adapter | Connection | PRO Compatible? |
|---|---|---|---|
| With auto-dimming mirror (all trims 2020+) | DCA-10B (10-Pin Type B) | Underneath plastic mirror shroud | No — 5th gen chassis lacks constant power to this connector |
| With TSS 2.5 | DCA-12T (12-Pin Type T) | TSS lane-trace computer | No — Classic only |
| Economy mirror (2019 some trims) | DCA-7B (7-Pin Type B) | Back of mirror | No |
Connection Points Explained
Rearview Mirror
Plugs into the auto-dimming mirror connector underneath the plastic mirror shroud. USB output mounts on the windshield near the mirror — easy to access and disconnect. The most common install across all 4Runner generations.
Domelight Cavity
Plugs into the pre-provisioned OEM dashcam connector inside the overhead console. This is the same port Toyota uses for their dealer-installed dashcam. Lives entirely hidden in the ceiling. Driver's side.
TSS Computer
Shares power from the Toyota Safety Sense lane-trace assist computer near the mirror base. Does NOT connect to the mirror itself. Works even on trims without an auto-dimming mirror.
How to Install
Mirror Install (DCA-10B / DCA-7B)
- Tilt your rearview mirror down and remove the plastic shroud/cover
- Locate the mirror connector (10-pin on most trims) — NOT the nearby TSS connector
- Unplug the mirror harness
- Plug the Dongar adapter inline between the harness and mirror
- Route the USB-C cable behind the headliner to your dash cam
- Replace the shroud — done
Domelight Install (DCA-5A) — 6th Gen
- Pull the overhead console / domelight assembly straight down (requires firm force — it clips in with 2–4 red clips)
- Locate the white 5-pin connector on the driver's side, usually taped up from the factory
- Plug the Dongar adapter into the connector
- Route the USB-C cable to your dash cam
- Push the domelight assembly back into place — done

Same harnesses as PRO. Swap module & mount if upgrading.
What 4Runner Owners Are Saying
I got the Garmin Mini 3, and the Dongar Mirror Connector. It's super easy. The Tacoma was like a 10 minute install.
Very cool. I'm powering a Garmin with a Dongar right now on my '22 4Runner.
I also just installed the Dongar adapter in our 23 TRD Pro. Real easy to install, I don't have any need for video recording while the car isn't running or parked unattended. Used a Garmin Mini 3.
I just installed this on my 2021 ORP. It comes with a short USBC cable so probably dont need to buy one.
Dongar Technologies dash cam kit and Garmin dash cam mini 2 install - Easy installation 15 minutes and works perfectly.
Dongar Technologies adaptor for dash cam Garmin 46. Dash cam using auto dimming mirror power for clean look.
Just got it done. Took about 10-15 mins. I have a 21 ORP.
Looking at getting 2 of the adapters one for the 4runner and one for my wife's Tacoma.
Can get that Dongar adapter that taps into the auto-dimming mirror and free up the socket.

Frequently Asked Questions
Which Dongar adapter fits my 4Runner?
It depends on your generation. 6th gen (2025+): DCA-10B (mirror), DCA-5A (domelight), or DCA-16T (TSS 3.0 computer) — all trims supported. 5th gen (2019–2024): DCA-10B (auto-dimming mirror, most common), DCA-12T (TSS 2.5 computer), or DCA-7B (economy mirror on some 2019 trims). Use the Compatibility Finder to confirm.
Does the 6th gen 4Runner support parking mode?
Yes. The Dongar PRO and PRO+ both support parking mode on the 6th gen 4Runner. Use Harness 5A (domelight) for the cleanest install — it's the same setup as the 4th gen Tacoma. The PRO+ adds custom timers, voltage cutoffs, and energy budgets for maximum control over how long your dash cam records while parked.
Can I run two adapters at the same time on my 4Runner?
Yes, on 6th gen trims with an autodimming mirror. Use one Dongar on the 10-pin mirror and another on the 5-pin domelight — they're on different fuses. Perfect for powering a dash cam and a radar detector separately. For RJ11 radar detectors (Uniden, Escort, Valentine), pair with the USB-C to RJ11 converter cable.
What about the 5th gen with no autodimming mirror?
If your 2019 4Runner has the economy mirror (no auto-dimming), the DCA-7B plugs into the 7-pin connector underneath the plastic mirror shroud. Alternatively, the DCA-12T taps into the TSS 2.5 lane-trace computer regardless of which mirror you have — it's completely independent of the mirror type.
Will the Dongar work with my Garmin Mini / Viofo dash cam?
Yes. The Dongar outputs true 18W USB-C (5V/9V/12V) and works with virtually all USB-C powered dash cams. Garmin Mini 2/Mini 3 work great with both Classic and PRO/PRO+. Viofo and RedTiger cameras have non-standard USB-C — for proper parking mode detection, the PRO+ is recommended (it has dedicated 5V always-on + Parking Mode CC settings).
Is the 4Runner good for overlanding with a dash cam?
The 4Runner is one of the most popular overlanding vehicles on the road, and a dash cam is essential trail gear. Use it for trail documentation and trip reports, security footage at remote trailheads, insurance evidence for rock chips and trail incidents, and peace of mind on long trips. Dongar's plug & play install means you don't sacrifice a 12V outlet that you need for your fridge, compressor, or other off-road accessories.
