Side mirror signal light wiring
Hi guys,
Just bought used 2003+ OEM side mirrors with signal light. Trying to tap into the side blinker, but cannot tell which color wiring is + and -. Does anyone have wiring color for the side turn signal light? I might have to take one out and use multimeter to find, but wanted to check if anyone had this already.
My 2002 does not have mirror signal light.

On a 2002, you’re tapping into the fender blinker wires. The easiest spot is right behind the grille.
If I remember right, the positive is the grey/red wire and the ground is the brown wire. But don't trust me completely, car wiring changes. Definitely test with a multimeter or a test light to be sure before you splice.
