When hooking up an external pressure switch, How do you really know how it is wired in the VB ? Without dropping the pan ? What if someone else changed something in the wiring inside.....this trans has been rebuilt how many times ?

Since Mr.freeze doesnt have the external port for the 4th gear oil circuit (Located externally by the 2/4 servo), this all can be done off the 4th gear oil circuit off the VB which is very easy to do, most likely you already have the wiring there from the 4th gear oil circuit to the TCC solenoid.

The kit mentioned above can be used for internal and external usage...... wiring it to a fancy Green toggle switch on that there dash would really look cool.....your buddies would love it... make sure when ya cut the dash ya wear them there safety glasses, safety first....its as easy as when ya cut those nice holes in the bottom of your doors to put them there speakers in....getter done!!!
