Hey all, I just bought a 63 glasspar with a 68 evinrude Model#55873R Serial#J03806. The throttle lever & tranny switch {electric} {in the same housing} on the boat is toast and the seller provided a new one. I am wondering what the wiring color verses forward, reverse, neutral are any ideas? Plus tips to keep in mind while switching out the old unit for the new one? Thanks in advance, Denny
