I know there are 4 customer access wires they are red, white, blue, black. When I found those wires under the dash I also found 4 other wires can some one please identify them for me?

They are:
Yellow - ?
White/Orange Stripe - ?
Light Blue/Yellow Stripe - ?
Green/White Stripe - ?


I think the light blue/yellow stripe is a PTO signal wire and the green/white stripe is clean tach out. Can any one confirm these and know what the others are for?

 

Yes,
LB/YE = PTO signal wire to PCM.
LG/WH =CTO

In 02 there was a WH/LB that was a 12v supply to the PTO .But since you don't have that wire combo
need to take a 12v tester and chk with key in run pos for 12v ,it is fused by fuse 29 10amp.

sorry can't help you with other wires
