Hi
New member first post.

Just bought a 2023 XLT and was installing wire taps for switched power into the RVM wiring harness inside the windshield cover.

Since I could not find this on the forum, I thought I would share the specific wires I found for switched 12V and Gnd
(Headliner harness to RVM harness):
  • Black to White - Switched 12V
  • Blue to Grey -
  • Green to Black - Gnd
  • Purple to Yellow -
  • Red to Green -

The colors make sense if you slide the connector housing up and out of its holder and look at the headliner connector and see the corresponding wire colors.

So switched power goes to the white wire on the RVM harness (which goes to black inside the headliner) and Gnd goes to the black wire on the RVM harness (which goes to green inside the headliner).

Just thought I would share this info for anyone similarly looking to tap switched power for things like dash cams and radar detectors.
