I also suspect it may be the voltage coming from the ignition but can't be sure just yet. I'm going to pull the control unit again and get in there with the multimeter to find where I'm not getting voltage where I should be.

@DragginMetal - dk blue, lt blue, tan, yellow I think. I'll check today.

I'm starting to think that reconnecting all the ground connections would be a good start ( splice into all ground wires and butt and eye let to a new ground location ) There's two main locations possibly 5 depends on where you pick them up at ??/ I guess I would try and pick them up ( New Ground wire's) as close to component as possibly??/ To bad they don't give ohmage states VS resistance by dimension Per say on schematics ??/
