trim pump? 2 wire or 3 wire
I'm replacing my trim pump set up on my 95 272 baja. I don't want to buy the wrong set up, so my question is how do you tell if you need the 2 wire or 3 wire set up?
Does it go my the # of wires coming out the pump motor itself, or do you go by the control connector which plugs to the relays? Thanks Robert

Two wire or three is referring to the wires coming out of motor .On two wire ,up or down is done by swapping polarity. On three wire the ground is third wire and you apply power to either of the other two for up or down .....Blue is up ,green is down .

I didnt know there were 3 wire motors but it seems that if you wanted to use a 3 instead of a 2, all you would have to do is change the relay wiring to make them normal switches instead of polarity reversing.
Have a look at a 3 wire schematic and compare it to the 2 wire.
