Dashcam hardwire fuse recommendations for a 2022 xl

[Oldgaffer]

Hi all,

I want to hardwire a VIOFO A119 Min 2, but I am not sure what the best fuses are to tap with the HK4 kit.
Can anyone please give me what is recommended to use?

Thanks,
OG

I followed this thread:

This harness is also a good option to avoid the hassle of routing wires up the A-pillar:

No Mavericks come with power in the rearview mirror from the factory.

The harness taps into the dome light to provide power for aftermarket accessories like dashcams and auto-dimming mirrors.

Really! ... I read "somewhere" that trims above XL had powered mirrors and you could tap into them. I did not know about tapping into the overhead lights. Looks very clean, the only negative is no parking mode.

So many different sources telling me different things.

Can anyone verify they used these?

🟡 Yellow wire (CONSTANT power)

Fuse 21 — 7.5 A
Climate control / E-shifter module
True battery power
Stable, low draw
Proven safe for parking mode


Red wire (ACC / ignition-switched)

Fuse 11 — 5 A
Telematics control unit
Ignition-controlled
Clean wake/sleep behavior
No high-load or safety risk

As indicated in the linked thread above, I used a micro-3 fuse in position #1-2 for an ACC (switched) source. Nothing else is run off that position. 3 years now, in 3 different Mavericks, no problem.
