Trim Control Power.

This is a different purple wire, but they do seem to be popping up everywhere, lol.

So what do you guys think? I am about to replace the Hydraulic pump. I can't think of anything else it could be. All wires are connected and look good. Solenoid is new. Took the 3 button switch out of the equation by bypassing it. Still nothing but an occasional single click from the solenoid. Can't get the Stern drive to move up or down. Never get any noise from the pump?
