trim pump schematic

[asalford]

have a 140 merc with a trim pump that has the plastic resevoir.

the one that is in the boat now, some of the wires have deteriorated so, it is impossible to determine exactly how they were hooked up on the old pump. I am replacing it with a Nused trim pump.

the column trim switch has 4 wires, up/down, and a trailor button.

Does anyone have a wiring schematic or know from where I can get one?

Here's a link to the OEM service manual. Open the link scroll to the outline page and click on the letter of the section you want.

Should be section 5A, would have helped if you would have given a year.
