Hey everyone. I'm sticking a 95 mark viii motor in my 67 F100 and I'm confused on a couple wires. I had some help from a guy who sent me some diagrams but I can't figure out what a couple wires do. Plug c121m and c121f. Pin 10 and 14. The guy had them labelled Dcim + and Dcim - Does that ring a bell with anyone? What is the dcim? Thanks everyone.
