So wiring a radio into a 89 GM and for those of you that have worked with one of these before theres a main plug and then theres a 2 wire plug also. The Two wire plug has a yellow wire and an orange wire, of course the yellow is the constant 12v the orange is light illumination
now on the big plug theres also a orange wire which is for dimmer
The head unit only has one orange wire and its for the dimmer?
why is there 2 orange wires on the harness kit?
