I have a 1962 Evinrude Lark 40 HP manual shift outboard motor that runs well, but the wiring in the boat is a rats nest. I was wondering how to rewire so that I just have the bare minimum things, like start, lights and horn. The motor does not have tilt or trim, but is electric start. The wiring harness from the motor looks original and intact. I just need to know what to hook up from there to the dash. Any help is greatly appreciated.
