Re: trim pump testting question
 

Are you looking to do this through the soleniods or just straight pump wires?
The pump should have a green/blue/black wires comeing out of the pump motor. Black is ground.....green should make the pump trim down....and blue wire will make pump trim up.

If the solenoids are on the pump...then look where the blue and green wires are hooked to and right next to that should be another post thats hooked to the power bus bar. (the 12v that comes from the battery) you can jumper across those two connection to make the pump go up and down....
