I have a Mitchell Isuzu Shop computer program that has exactly what you are lookin for. I went to the wiring diagram of the stereo/cd player and right clicked on the diagram....and it wouldn't let me copy it or save it. So I took a digital pic of it...but it looks like $@*%.

Sorry, but I tried!! What I can tell you is this:

Wire from CD-----------------------------RADIO
red------all to noise filter--------------NCA #12
Black all to noise filter----------------VIO #8
yellow---all to noise filter---------------Blue #5

Grey-----------------------------------------pink #11
whit-----------------------------------------vio/wht #10
gry------------------------------------------red/blk #9
grn--------------------------------------------grn #7
blu------------------------------------------blk #6
org-------------------------------------------yel #4
pink----------------------------------------wht 2
vio------------------------------------------red #1
----------------------------------------------Brown (not used)

With all that being said.....it should have wiring harnesses that do all that for you.
