Need help from Yamaha guys.
 

Here's the deal. I bought a 1990 150hp Yamaha motor from a guy and seen the motor run and tilt/trim worked. I made the deal with him and he pulled the motor off his boat the next day and I went and picked it up. He gave me another set of controls and oil tank as he was putting a 200 Yamaha on his boat.

I have a few wires and plugs I'm not sure where to put. The 10pin plug went right it. Motor turns over, choke works but the tilt/trim aren't. I can hear the relays clicking but the motor doesn't move. I took the blue wire straight from the motor and touched it to the 12v wire at the starter and it sparked like crazy and got very hot.

I have the + & - hooked up correctly. There are 4 wires that appear to be coming from the trim sending unit that I assume go to a gauge which I do not have. Could this be part of the problem?

Also the connector on the oil tank harness from the tank is a square connector. However there are no square connectors on the motor. Or is there a connector with the same color of wires. This is a project I'm looking to sell to buy some goodies for my new V so I really need to get this figured out quick and cheap. I'll attach some pics of the plugs on the motor. Maybe someone can help me out so I can get going on the V.

The black plug has a black, blue, brown? & gray wire. The green plug has a yellow, yellow/red, green, green/red.

These four wires come from the tilt/trim area. They are black, gray, orange and pink

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.
