We just bought a sweet boat. Only the wiring was totally fried, Gutted it out, Bought a similar (82 Bayliner Volvo 4 banger) Harness. The Trim box and switch were bad on the old and included in the new... However, I have a 4 wire female plug coming off the trim motor and only 2 wires coming from the Box, Is the newer trim setup just wired differently, if so can I just jumper the motor? Colors are brn, black, blue, and green/yellow. Also, I have 3 wires going to trim sw. but only 2 are used.?? 12V in center pole is wired directly to the dash. One more question, The dash has an AMP meter on it and I could not find any mention of that in manuals, I just want to be sure in rewiring so this wont happen again.

I'm afraid I can't offer any help, but I'm interested in your outcome. I have a related issue with an '83 Trophy:

Thanks Don! Do you by chance have a P/N (or spec) for those relays?

EDIT: Found it. For future readers it's Volvo Penta P/N 876037 (Relay Kit).

Ok, I have that schematic already, but it shows 3 wires coming from the motor and I have 4 from the motor and 2 from the trim box. Also I don't have a space for a warning light so that's why only the 2 of 3 wires being used on trim switch line.

Might have a look at this wiring diagram for a 4 wire motor, but it's for a 280. Wouldn't really surprise me if the whole thing got changed out by a previous owner. Lots of things can change in 35+ years.
