Wiring Question

[Skools Out]

This is what i've found out so far more to come tomorrow after i find my master marine wiring book that has all motors and acc. from 1968 to 2004
1-2-3-4
8-7-6-5

the first 3 below are tach hook ups:

Purple wire goes to pin 1
Black wire goes to pin 2
Gray wire goes to pin 3

Grounding these pins, will activate the following:

Pin 4, turn on no oil lite
Pin 5, turn on low oil lite
Pin 6, turn on hot lite
Pin 7, turn on check engine lite


Pin 8, is used to activate the warning horn, it supplies a ground to the horn circuit when any other warning circuit (pins 4 thru 7) is grounded.
