Need help from Yamaha guys.

Update. I figured out the small black plug is for the oil tank and the guy just gave me the wrong harness. The wire colors on the tank itself are the same as the harness on the motor.

pull the big green wire and the big blue wire from the relays, put 12v positive to one while grounding the other, the trim motor should spin, if it doesnt, reverse the leads and see what happens, you have to remove the leads from teh relay, as in the relays at rest position, it grounds both leads, If the trim motor doesn't spin, it bad, if it does, connect one lead back to the relay, put 12 volt positive to the loose lead, the trim motor shold spin, if it doesnt, the relay is bad or there is a lost ground in the harness. Hook teh otehr lead up at teh relay, pull the last one loose and hook 12 v positive to it, Same deal. You can check the relay itself with a test light. At rest, both post out of the relay should be grounded(hook the lead on your test light to a 12 v positive source). Check this with the leads to the motor disconected. Activate teh relay by holding teh trim switch, check that direction(green down, blue up) for 12 v positive at the corrisponding terminal, and make sure its not loosing ground on the other terminal. Having two test lights, one hooked to positive, the other to ground makes checking this easier.

Ok figured a lot out today. When I got the motor there was already 1 red wire on the solenoid where the 12v supply goes. I added the 12v supply and went on about my business. However turns out there's 2 red wires that go to the solenoid as well as the 12v source. Hooked that up and the tilt/trim works flawlessly.

Still trying to figure out what the green plug goes to.
