Been retro fitting the vectra c auto dimming mirror today and i managed to wire up the IGN live, ground and multitimer wire but i couldnt find the reverse wire for love nor money.
I pulled the X1 connector (passenger side kick panel out) but could see no white with black trace wire going into this.
Does it switch colour when it comes from the REC to X1?
If anyone has a pic of it at fairly close image so i could see the position or even the pin numbers that might help me greatly.
The mirror works fine at the mo but would like to stop it from dimming when reverse is engaged.
