Wiring issues

[brian2586]

I just mounted a new outboard on my boat and am stuck on the wiring. For the most part the colors do not match. I'm going to list the colors of each and hopefully someone can make sense of it for me. Thanks for the help.

1975 Sun Ray Tri-hull wiring harness colors:
Red
Black
Orange
Gray
Tan with orange stripe
Yellow
Brown

1989 Merc 50 hp harness colors:
Red
Black
Gray
Purple
Tan with blue stripe
Tan
Black with yellow stripe
Yellow with black stripe
Yellow with red stripe

Re: Wiring issues

Here are the Merc harness colors. Not sure what the Sun Ray colors are what type of controller is it? Or what motor was on it before?

RED Un-fused Wire from Battery
BLACK GROUND
GRAY Tachometer Signal
PURPLE Ignition (Switch) to 12 Volt Positive
TAN / /BLUE STRIPE Alternate Color Temperature Switch to Warning Horn
BLACK / YELLOW STRIPE Shorting or Stop Circuit
YELLOW / BLACK STRIPE Choke (Enrichener System)
YELLOW / RED STRIPE Start Switch to Start Solenoid to Neutral Start Switch

Re: Wiring issues

Except for the tan/orange wire, the rest look to be standard merc colors from 1975. In 1975, red was +12VDC, Black was ground, grey was choke, orange was ign killer, brown was tach, yellow is starter solenoid. You are missing ign accessory power which was white in 1975

Re: Wiring issues

Thanks guys. I think I have it figured out. But now I've noticed that all the boat wiring is rotted. And now I'm having trouble finding just a generic harness for the boat. All the motor wiring is fine. It's just a 8 pin connector. Anyone know where I can get one. Thanks.
