I'm installing a Bowtie Lock-up kit and 4th gear pressure switch has two contact for the wire connectors, however the direction do not state what connector pin goes to what wire. You have one (Red) wire that come from the self grounding solenoid and the other (Red) from Connector case. The numbers on the back of the switch is 1, 2, F, and 4. The F and 4 are in line with the connector pins but, which wire from self grounding solenoid and case connector goes where on the 4th gear pressure switch. Maybe it really dont make a different?

 

I wired mine like this, but the switch was Normally Open, NOT
Normally Closed as in the drawing. The hot wire (ignition key to ON) from the case connector goes to one side of the N/O 4th gear
pressure switch. The wire from the gronded TCC solenoid goes to
the other side of the 4th geard pressure switch. When tranny shifts to 4th, the N/O switch closes and the circuit is completed.

I guess it really does not matter what wire is hook up to what side of the connector on the 4th pressure switch.
