On the right side of my merc 40 engine, facing it from the rear, is an
UP/DOWN rocker switch. Is this a power trim? Didn't see if it worked when
I had the motor running, and today when I pulled the cowling looking for
engine SN, I noticed some wires had been disconnected there.

Right now, I figure by the engine number that it is an '89 ELPTO. (Electric
Start, Long Shaft, Power Trim, Oil Injected)

Thanks.

If it's on the cowling, it's most likely an electric/hydraulic system to
tilt the leg up. Check on your throttle and see if there is another switch.
If it has one, it can be used to trim while underway.

It's to operate the trim/tilt from the back (an option to make it easier
when you're behind the boat on the trailer). If it's unplugged, water
may have gotten inside causing it run run when it wasn't supposed to.
