Hello, I have a 1977 stingray w/140 mercruiser serial # 4661246
Is a 181 ci. 4 cylinder. Does anyone have a wiring diagram for this I/O
I have a mess-o-wires and don't know where they go?
Any help is greatly appreciated, thanks.
While the link above will probably work, it's for the 90 to 97 years. Here's a link to the service bulletin for wiring diagrams that are supposed to be in the service manual for your year engine.
Thanks Terry, I may be able to figure out something from this, but wire colors do not match up w/mine I have no yellow/red wire and no purple wire. can't figure this one out????

If you DO need to do any rewiring for the enging, spend the extra $$ and color code the wire to match the service manual, it will make life 50x easier to diagnosis in the future. Instead of All one color for everything. Good Luck
Hello, I am in similar need, I have a 75 Imperial using the same wiring diagram as the early model one you posted. If you could help me out with a diagram for the gauge side of the wiring and one for the trim pump I would appreciate it, cause everything I am seeing is telling me that I am missing a Trim solenoid somewhere
