Rear View MIrror Options

I don't know what wire it is, but there is a constant power wire for the OEM Homelink console. You have fuse boxes on either end of the dash so you can check those for constant power to tap into.

Can anyone confirm one way or the other if the 2023 1500's have the harness with connector up behind the headliner or not? Just bought the mirror # 13540313 and I'm trying to figure out if I need to get that pigtail or not. Thanks!!

From what I have read of those with a 22.5 refresh truck, they DO NOT have the mirror harness in the headliner. With the Global B electrical architecture change, they dropped that part of the wiring harness for some reason.

Thanks!! One more question for the experts. Seeing we are going to need to tap into the wires up there, does anyone know what those little spades are that they use for the Radar detector leads. Little flat ends that you can push into the connector. Been searching around Amazon, and all I'm seeing is much too big. It think i'd much rather go that route than to tap the wires themselves.

Look for Micro 2 fuse taps.

I am talking about these mini flat spades that fit right into the molex connector that folks use to power radar detectors from the mirror connectors. With these if I can find them, I can get the pigtail, and use these spades to Roof Console connector right there.

Fwiw, this is what I did that worked out great for my 2023. The Black Roof Console Connector X2 has the Ground (Blk/Wh) at Pin 5 and Switched Power (Purple) at Pin 8, as mentioned earlier in this thread. This is the connector closest to the driver when you drop the overhead console (the other connector you don't use is gray).

I got the connector with the pigtails that fit the mirror PN# 13540313. The link is a page or two earlier in this thread too. After confirming the wiring and tested, I simply unwrapped the cloth tape a few inches, and ran a razor blade around the Blk/Wh wire in two places approx 1/4" apart, and tightly wrapped the Black wire from the pigtail then soldered. Same for the Purple wire and wrapped the Red from the pigtail, and soldered too. Wrapped both leads tightly with electrical tape, and secured with some small nylon zip ties. I don't believe there is a Reverse wire available up there on the Refresh, so I didn't use the green lead from the pigtail.

Entire project took about 30 minutes. The hardest part is getting those two T15 console screws back home. Thanks to all of the earlier contributors for making this an easy mod!

Sorry for reviving an older thread, but I just picked up my 2021 Sierra Elevation

I picked up a Gentek mirror with homelink, autodim and compass with a 3 wire hook up - ground, switched power (Compass) and 12V (homelink). I was going hook up compass and homelink to switched power.

I have the unused autodim mirror connector glued in my overhead console. I clipped it off and checked all the wires but couldn't find any power at all (switched or constant). Any ideas/suggestions?

Before i order the fuse tap from Amazon, thought I'd check to see if I was missing something....
