Re: 700r4 lockup help

The first diagram made no sense to me, power goes from switch to A then to TCC, then to pressure switch and stops? I dont even know where the solenoid is, but if I did and it gets power from A like I think it does, then why would it go to the pressure switch?
I am running switched power to the two prong pressure switch I put in the 4th gear pressure port. Presumably when 4th shows pressure it completes the circuit and sends power to A.
The other wires at that plug are B and D. Read various things about what to do with them, I guess no one truly knows. I cut them and tied them together per one sources advice, that blew fuses. Untied them and put D to chassis ground, stopped blowing fuses and the lockup worked properly one time, then hung up again.
My tv cable being wrong could probably cause pressure issues making the pressure switch not work as intended, and failing to power the TCC, right?
