Ok in from playing with it and one thing I noticed is that with everything hooked up, I am reading a ground on the opposite terminal of the #2 fuse. I hook up my test light to the power in side, and touching the other side I get a light. With the C2 on the TCCM unhooked, I do not get a ground. So I am sure that I am reading the ground from the connector through the TCCM. What I don't know is if that is normal or not.
