Seeking help hard-wiring a dash cam into '24 LT Trail Boss

916TrailBoss · December 15, 2023

I have a VIOFO A129 dash cam that I would like to hard-wire into my new truck. I had it hard-wired in my 2019 RAM previously and it worked great.

I can figure out how to run the wire as it is similar to my RAM. But I don't know what fuses to tap into. My wiring harness is for the Micro2 Blade Fuses. Previously I had it tapped into fuse that is powered all the time and a fuse that is powered only when ignition is on or in accessory. Can someone please help direct me to what fuses I should use.

Here's a more detailed description of the fuses. I need a constant and switched.

Most tap F26 as the switched / accessory which requires a micro 3 fuse tap (amazon). The constant power can be F8, but the issue with that fuse is that the power is running on the right lead which makes placing the fuse tap in the proper orientation very difficult as it gets pinched next to that big adapter in the middle.

I tapped fuse F42 as the constant as it allows proper orientation of the fuse tap (power is also on the right lead).

I tapped into F32 for the "keyed" accessory wire and F26 for my constant hot wire. Both require the micro 3 fuse tap. I did this both in my 2022 (refresh) and my current 2024 trucks. Both worked great.

Unfortunately, I didn't see the above posts before resolving it today.

I used fuse F42 (Electronic Park Brake Switch) 10-amp Micro2 as my constant.

Using a circuit tester F26 (USB Ports/Special Equipment option Retained Accessory Power) 10-amp was the only fuse switched. It also uses the 3 prong fuse however the fuse harness I got on Amazon didn't fit. I had to use a file to shave down the edges all around to fit in the fuse slot. Once I did that it work.

Hopefully this will help anyone else with a 2024 Silverado.

Not sure if your 2024 will have different fuse locations. But I used F3 for constant power and F20 for keyed power, from the passenger side interior fuse panel.

Here is my install video for a Blackvue DR900X-plus. Hope it helps...

The 2022 (refresh) + trucks are different than the pre-refresh trucks. There are 2 post above showing which fuse locations for the refresh trucks.

With your key off use test light to find B+ on both side of a fuse this will be your power all the time. Next up your test light to find B+ when you turn the power on. This fuse will have power on one side but not the other side, until you turn on the key . Then it will have power on both sides of the fuse. Your ground will be to any good metal surface that is under your dash or around the fuse box. And the you ready to go. I would use a add a circuit to both B+ use the same amp fuse that was originally in that spot

Did you not read the thread? It’s already been resolved.

Also F3 and F20 are dead on the new Silverados.

Can you provide a picture of the fuse box with the taps? Also, you said f26 was your constant. I thought that was the switched.
