When I started working on the Blazer, I noticed that the wiring was butchered up. Because I only needed the factory harness to work the lights and wipers, I decided to cut out all the factory crap and use the firewall junction as a gromet. The problem is.. I did this last year when I did the motor swap, and forgot which wires are 12v and ground on the wiper motor. I don't have a vehicle (87 Blazer) close by to test off of, so can someone who has a similar vehicle, and feels comftorable with wiring, let me know which wires do what...
Thanks to anyone who could help, and don't hate on my MS Paint skills!
