Where to find a wiring digram for 1988 Grumman Pontoon Boat 20' 70hp Johnson?

i have a 1988 grumman pontoon boat 20' with 70hp johnson outboard. I recently changed all new carpet and interior and apparently a few wires were crossed. I need to find a wiring diagram or just know how to wire it from the ignition back to the motor and battery.|||This might help you, I don't have the wiring diagram for a 70 HP, but here are the diagrams for a 40%26amp;50HP-1986 and on

If you buy a seloc repair manual for your engine, the wiring diagrams are in the back of it.|||boat wiring harness:


keyswitch terminal B - red/purple


terminal A - purple


terminal M (raised) - black/yellow (emergency lanyard in parallel)


terminal M (not raised) - black


terminal C - purple/white


terminal S - yellow/red (neutral safety switch in series)





gray - tach sender


tan - warning buzzer





need the wiring on the engine side of the harness, just ask!
