2017 XLT - Rear-view mirror wire harness

[Thunderwink]

I've searched numerous threads, but I haven't found an answer for my 2017 XLT.

I'm trying to do a power wire tap for a radar detector, and I cannot find a diagram that is correct for my vehicle.

Anybody know which is powered (switched) and which is a ground?

Many thanks in advance.

Welcome to the Forum.
I'm guessing you don't have a meter. That would make things little easier. The following post mentions a light blue/white and a black wire. That is from a 2014 Owner. It is hard to see but it looks like you may have those as well. http://www.explorerforum.com/xenfor...ing-radar-detector.316759/page-6#post-3366911
Did you see this thread? It is a 2016 which should be similar to a 2017, I think.

Thanks. I hadn't seen that thread before. Maybe I'll just tap into map light instead. I'm not sure the pins on the tap wires I have are narrow enough to slide into the harness anyway.

Oh, and my comment on the radar detector debate on that thread: perhaps it's an urban legend, but I've heard there have been studies that show that drivers using radar detectors have fewer accidents, presumably because they are more engaged and invested in their driving. That's my case. I've been using radar detectors accident-free for 30 years.

Here you go, this might be helpful as I tapped into my RVM to hook up my dashcam.

Thanks. I did find this thread, but found that my wiring was totally different than the diagram in that thread.

I have the same rear view mirror wiring harness as you.

The blue wire with the brown stripe is the 12v positive, and the blue wire with the white stripe (above it) is the 12v negative.

This circuit is only live with accessory power (or when the vehicle is running).

I hardwired my dash cam into this circuit earlier today.

Did you also check the cabin fuse box?

I looked through my user manual and didn’t see any fuses connected to back up cam or mirror.. should I pull every fuse and check each one

I checked and didn't see any either except possibly #36 EC mirrors. I wasn't sure if that included the inside rearview mirror.

If by "scanner" you mean a OBD-II reader, that might give you a code.

Yes , ran obd-ll no codes

 

[javaleo]

If you used a simple/ generic OBD II scanner it will only give you the generic codes, things like a check engine light, (emissions), ABS (maybe). Like the ones AutoZone or Advanced Auto user to read your codes.

The camera is going to be part of a "Ford" module, and you will need a scanner that reads those modules.

It was the # 36 fuse … man what a place to put a fuse box … thank you
