Default Yamaha 150 Oiling Problems

Having problems getting the remote tank to fill the engine mounted tank. The manual override switch works, so the pump on the remote tank is fine. Replaced the float switch on the engine mounted tank, didn't help. The float is working, as the low oil alarms are functioning as oil is drained out.
Checked continuity of the wires between the plug after the computer and the remote tank, good on all four wires.

Question is, checking between the plug before the computer to after the computer, one wire (before computer) will feed three of the wires after the computer. One wire (blue/green stripe) before computer does not feed any of the four wires after the computer.

My feelings are a bad computer, any thoughts before I take it in and have it looked at. Motor is a '96 150 Precision Blend.

I've read through the archives and understand how the system works. It's not the trim indicator, as this has not worked for awhile.

Ask Sim (Andy) on the vendor forum Shipyard Island Marine Engines. I expect he's run into this before and can get the right part to you, too.
