I'm trying to wire up the reverse lights on my 2015 style tow mirrors. Does anyone know which wire the reverse lights are in the bcm under the steering wheel? I don't have access to a circuit tester. On a 2001 Sierra

Sorry no help but do mirrors have tow lights? Try a search in electrical might find a schematic drawing but now I`m curious about tow lights in mirrors?

Do you mean reverse lights? The 2015 K2xx model mirrors do.

Perhaps it is to be found in this:

Yes, the new style tow mirrors do have reverse lights lights however you want to wire them really.

Yes now I remember them on a 16 2500. Do you or anyone know if those mirrors can be installed on a 08 2500 I really like them.

This should help. There's a link to my thread in there as well.

Here's a photo of the box

Yeah that's odd it's not setup the same as mine.

You could take a multimeter and test the other wires and see if one is hot only in reverse. If not, then you may have to grab the reverse wire coming out of the bcm.

And for that I'd have to look up a pinout of the bcm connectors. There are several other ways to do it as well. But the bcm and the junction box are the easiest in my opinion since they are right there.

Right thanks. I may end up just wiring it into the fuse box with a fuse tap but well see
