Q about T/C lockup wiring, please help

It took me all damn day but I finally got the Transgo Reprogramming 2&3 and the shift Kit in my 700 today. What a PITA.

Anyway my question is this, my car doesn't have a computer but I am keeping the lock up convertor. The other night I was talking to dana about it and he told me how to hook it up but I think I forgot, this is what I remember.

Run a hot wire to the terminal A on the plug in at the trans. that wire goes to the solenoid, then a black wire goes to the (I'm going to call it a pressure switch)on side of the valvebody, and it needs to be naturally open. I am about 80% this is what he told me to do.

When I apply to the A terminal it will power the solenoid and lock the convertor up, I have the power wire hooked up to a vacuum sensative switch. What does the black wire going to the pressure switch do?

Any help would be appreciated, I am planning on putting the trans in tomorrow and I want to have it right, if its not I will drop the pan after I find out.

Thanks
Jason

If you wanted, you could hook up a relay to lock up your TCC in 4th only. This stops the annoying lock/un-lock in 3rd. If you want to do this, reply, and I'll check my wiring again.
