That's good progress!

Disconnect the 14 pin connector and press on each of the male pins to ensure they are firm and not pushing into the connector. Inspect them for any corrosion or carbon. Pull the back off of the engine side of the connector (be careful the pins don't all come out) and inspect the solder joints where the wires connect to the pins. Make sure they are not frayed or loose. Pay particular attention to the yellow wire. Slide the chassis side out of its mount on the fuse panel and do the same thing. It sounds like you have a loose connection, cold solder joint, or loose pin. Now wasn't that better than dropping the engine? Good luck!
