I dropped a 350 in the old girl, and the shop removed most all of the old wiring from the I4. They also pared back the wiring for the Back up light switch on the Tranny, and the 4x4 engaged switches on the np-231 and dana front axle. I've tried finding prints that tell me what the color codes are for these, and the best I could find was black and yellow for the 4x4. Found one wire, and when 12 vdc applied, nothing. no indicator, nothing. Anyone have any ideas?
