Control wiring pig tail for quicksilver

[Billdo5150]

I have a 1998 mercury 135 black max

Trying to find out what the color wiring scheme of the pigtail in the picture. I need to hook up my tac, trim and can I but a temp gauge with the wiring that’s provided in the pigtail.

The tan wire should be the temp gauge sender wire. On the Merc V6 motors, one cylinder head has the overheat switch, the other has the gauge sender.

I believe that the harness that fits that plug is A-84-86398A4.

Was that the question?

So which color is the color for the tac and trim?

 

[Chris1956]

Tach sender is grey. Trim sender is Brown/white. Overheat switch is Tan/blue.

It sounds like you should inspect the trim sender, temp sender and tach wire on the voltage regulators, to make sure they exist and are pulled thru to the control.
