help needed

[mike77v20]

i have a 77 with a straight six was looking for a wiring diagram for it as far as trim pump motor the wires that come out of throttle contol and tach and fuel gauges for the tanks my wiring was in bad shape when i got the boat p/o did a hell of a number on it

can't remember if the older ones used the same colors, but red wire is power to the switch, blue is up(think blue sky), green is down(think green grass), purple is the trim limit/trailer switch, most of the time, the trim limit switch is bad and most people just bypass it(it interrupts the blue wire)
