i need to patch into the 12v signal for full beam located at the rear of the Impreza headlight. Which colour is it?

cheers

 

Why ? be carefull when you do it as the scooby headlight system isn`t the same as most cars, there is an ignition switched live on
the red and the dipswitch switches to earth.
tell me what you are trying to do and I will see if I can help.
Have a good one
