Re: 1988 mercury control

Colors should match if your boat was wired to BIA code.

Get a maintainance manual. It has all the diagrams in it.

hope it helps

Striperguy, If the plug is the three connector type, it will normally be Ign accessory (+12VDC), ground and tach signal.

i wired it color to color and know the only way it will start is if i hold the trailor button in at the same time i start the engine, and the same thing for the trim is this right, not familiar with these controls. thanks for the input.

Re: 1988 mercury control

Clearly your wiring is incorrect. Ign switch and trim switch get unswitched +12V (red). Sounds like you need a wiring diaghram.
