You have 2 trim buttons. One on the shifter handle, another on the outbaords lower plastic cowl. Each trim button has 3 wires on it. A red, a blue, and a green. Red is power in to the switch. When you hit trim up, the switch combines red to blue, when you hit trim down, the switch combines red to green. An easy way to remember this is blue is sky, and sky is up, blue is trim up. Green is grass, grass is down, green is trim down. Both switches will send power down the blue or green wire and that power goes down to the trim relays on the engine. The problem is going to be 1 of 3 things. Either the trim relays welded their internal contacts together. One of the trim buttons is bad. Or there is a short between the trim switches and the trim relays, and those blue/green wires are picking up power without the trim switch being depressed. The switch on the outboard is easy enough to disconnect to rule that out. After that, you can either check for power at the trim relays on the small blue and green wires that go to each relay, or, you can just replace the relays (they are 20 bucks each) and see what happens. If you do check for power and find none on those small blue/green wires, then the relays do in fact have welded contacts. If there is power, then the next step is disconnecting the trim switch in the shifter handle and see if power goes away or not. If it does, the trim switch in the handle is bad. If you still have power with that switch disconnected then you have a short in the wiring harness someplace. The short can be anyplace in the harness on the engine or in the extension harness that runs between the outboard and shifter, but I can tell you that 99% of the time that when there is a short, that short is almost always inside the shifter handle itself, at the base of the handle where the wires that go to that shifter button. So if it looks like there is a short as you get into troubleshooting this, look at the base of the shifter handle first for the short. Does that all make sense.
