Goole is your friend...I just googled 85 nissan pick up radio wiring and found this http://www.justanswe...ickup-when.html
Yes i found that, but i dont have any white wires. Or green ones. So that is no help.
EDIT: Btw i found a multimeter so after work i will probe the wires and see what i can find.
