Hey everyone. I bought a clean '88 3+3 crew cab dually. It was an auto truck but I'm putting in a nv4500. It has a mechanical speedo. The nv is electrical. I was thinking about buying new autometer tach and speedo to replace the dash. What do I have to do to wire up the speedo? Do I need the original wiring from the nv? (Which I don't have.) Or can I wire myself?
Thanks for any help
