Back of the rearview mirror — power vs. ground

[amongmany]

Can anyone confirm for me which of these is power vs. ground? I don't have a voltmeter (or frankly know how to use it). I'm sure I can buy one and figure it out, but if anyone can help me determine which is which it'll save me time and a few bucks as I got to install my invisicord.

I think you have a different year than mine (2004). On my 2004, it’s the same harness, but pin 7 is positive (green with a blue line). Pin 6 is negative (white with a black line).

I’m guessing your pin 2 (white with black line) is negative. If I’m wrong, you should blow the IG1 fuse, it’s 10A.

Actually mines an 04 as well. Thanks for the input.

Should have searched more carefully; found my answer here: Lexus GX470 - Radar Detector Hardwire
