I'll have to go out to my boat in storage to get you some better pictures. To the RH side of the steering wheel you have horn, dash lights, and navigation lights. ON the LH side of the steering wheel you have blower, trim, and tilt. I rewired mine though so tilt and trim are on the same toggle. Basically bypasses the trim limit switch. Sometimes you just need a little more trim and trying to lift up on two toggles at the same time at full speed is a little tuff.
The trim switch on mine is where the horn is on the Volvo drives. So does the Volvo only have two toggles to the right of the steering wheel?
