Mirror tap gone wrong..

I tapped into the rear view mirror for a V1 Gen2 and crossed the wires initially. I now have the detector working but all my constant on options aren’t working until the truck is started. I can’t seem to find a fuse that is blown. Trying real hard not to take it in to the dealer.

 

Please change the title as HELP is for people that are stuck.

 

Apologize new to the site

 

Yes , still nothing. No remote door locks doesn’t keep anything in memory. No emergency flashers. Anything you can run with the truck off is not working until I start it.

 

I'd start by checking ALL the fuses under the hood and behind the dash.

What wire did you tap into? I could look at a diagram and possibly help you out.

 

The rear view mirror. There are three wires, the blue is the constant on. Beige is power with ignition on and the white/black is ground. I crossed the two power, which is the issue. It has to be a fuse(I hope)

 

This is the schematic for a 2016. But the Blue wire is also shown as unswitched here. So maybe it's the same fuse in your truck? What year is your truck?

 

Here is the wiring diagram (for a 2017). Check those two fuses first.

 

I have a 2016

 

Look for that "10amp ECU-B No. 3" fuse shown near the left side on the schematic. Sorry, I don't know the physical location of the fuse.

 

The wiring should be the same.

 

Here is the location for that fuse.

 

Well? Any update?

 

I will remove and check all fuses when I get off work today 3:00 cst
Thank you guys

 

Just a few things it provides juice to...should be "less" in a '16.
Not many read, only after they FU things. PSA_FYI-Ground terminal from battery

 

Thank you all for the help. It was the center number 10amp fuse under the hood. Glad I joined this site! Really appreciate you guys

 

I mistakenly crossed the blue and white wires on my rearview mirror too, ugh!! Thank you all for offering the solution and pointing out that it was a fuse, and where it was located. This has been eating me up all day and it solved my problem!
