I want to install my x line boost gauge made stri motor sports electronics but I dont know where to get all the electrical wiring from.
red wire 12 volt ignition on (i can figure this one out)
blackwire Ground (that's easy)
yellow wire light source 12 volt illumination (I have no idea)
This is a 08 Spec B and a lot of the docs want to use the trip computer wiring which I dont have that trip computer so I am not sure where to get the proper connections.
Can someone point me out to a post or some better docs?
