I have found that the engine wiring for this motor is specific to 1985 only. Does anyone have a color coded engine diagram for this specific motor? I have a bunch of manuals that cover these years, but I don't think that any of them matches what I have. The wiring harness in this motor is obviously 37 years old and the wiring insulation is brittle and faded to the point that I want to make absolutely sure that I get the correct connections. I found two or three wires that were broken at the exit of the red plug, that was just making connection. I was doing a little work checking out the motor and had to move the plug. When I put things back together, I had absolutely nothing. Checked the fuse and it was blown. Inspected the "hard bend" at the red plugs wire exit and found two wires completely worn off and enough of a mess to potentially short everything out.
I have purchased a replacement engine Harness from CDI (413-3590) but because it is not the original "Big Red" plug, there seems to be some extra pins in it the the Big Red plug doesn't .
Currently I am under the weather and haven't been able to get out there and see if I could hand trace and match the existing wires to the new Harness. My fear is that I don't to end up burning up the Power Pack, Rectifier, or something else expensive!

Crosbyman, thank you so much for the quick comeback. I want you to know that I have accessed this site and dismissed it because it didn't not show a listing for the Johnson 120 or 140 Hp Motor under the 4 cy 1985 motors, only the 90 & 115 HP motors.
However, I have decided to look deeper into the 90-115 models as they are specific also to the 1985 models.
Thank you again.

I believe the wiring should be the same.

I agagree they are not exactly 1985 /140s .... yet I suspect they would have lots of similarities and you can probably hook up most of the wiring.
