Looked up and it's a water temperature sensor code. Popped the hood and the red wire on the high idle connection at the thermostat broke off at the connector. Don't worry, it's an old unit from Yankneck. I unplugged it and plugged the original connection back and the check gauges light is out, but the code won't clear. Maybe need to disconnect at the back of the head too...the one I can't reach myself. Need a gal or a guy with feminine hands.

I would return it back to stock and then clear codes.  

 

I don't remember how Ed's switch worked in terms of powering things.
