I have a mid '80s Cadillac rack and pinion I want to put in '39 chev. The pinion tower (and I assume the power steering valve) has a pair of wires (red one and green one) w/connector that probably went to the computer in the car it came out of. Problem is I have no idea what they are for, or if the rack and pinion will work without a computer hookup. Have started building the mounting brackets for the steering, but I might just have unusable junk and need to go junkyard crawling to find steering set-up I can use. Anybody got any good ideas? Any help is always appreciated, and I don't mind a little ribbing about not knowing these things. Most my cars are older than I am, and back then they didn't have computers and such. (they didn't even have seat belts, if you can imagine that). Thank you.
