- Thread starter Ttypemike

factory radio 86120-351701999 LC. Every wire diagram I find online doesn’t seem to be accurate. Can someone please tell me what’s the function and colors of these wires?
It is. The radio is a cd/cassette am/fm.

Hi. The colours on that plug look very similar to the ones on the Pioneer head unit you are trying to fit. Can you use a multi meter and check which wire is what? If I remember on the pioneer unit I fitted :-
Orange was for illumination (dimmed the display when turning sidelights on)
Red was ignition feed
Yellow was permanent live to keep memory on radio (for presets and settings)
Blue was the feed for the electric aerial (If you have two blue wires one switches the amp on for the rear speakers or sub woofer if you have one fitted)
Green and Grey wires are for the speakers front and rear. To find which wire is for what speaker you can removed the door cards and have a look at the speaker connections.
Cant remember if white is the earth or not.
Pink dont know that one
With a meter you should be able to sit in your truck and try each wire with ign on and write them down. Bit long winded but its the only way to be sure.
The colour code for my Colorado was very similar to the Pioneer unit and was quite easy to sort out. HTH
