Mercruiser Pre Alpha trim senders wiring schematic

[nic420]

I am rebuilding my trim senders limit and position. I do not know where to hook up the wires once you pull them through the transom. I have the manual but it doesn't say anything about the wiring. Please advise.

Hi there, What year and engine model are you working with?

Do you have two round pucks on the outside gimbal ring? Or do you have the hydraulic sender unit inside the boat?

The Trim Limit wires run over near the trim pump and plug into the blue and purple wires.
The Trim Position wires will attach to a ground and a brown wire with a white stripe (gauge sender wire).

Here is the late model wiring diagram


Wires for the position sender goes to gauge (brown/white) and other goes to ground (black), doesn't matter which
