I just purchased a kick down pedal for the th 400 in my 78. The truck originally had a th350 so i am not sure how to wire the pedal up between transmisssion and wherever else. All responses appreciated.

Brothers. One leg of the switch goes to B+ via any connection in the fuse block that goes on and stays on with the ign on. Ign 1 or 2 should do nicely. Next, the wire goes to the connector on the side of the trans. I am assuming it is NOT a TCC unit. The connection on the trans for forced downshift will be a single wire male connection. Hook it up, adjust the switch and road test. You should be good to go at that point. Jim

Almost 2 years of work, but it was really worth the effort. Little stuff left to do is mount winch, wet sand & buff out and build belly pan\running boards. Body work takes lots and LOTS of beer!!!! God, Guts and Guns made America and God, Guts and Guns will preserve it! The worst thing you could do is get into my sights, but that don't matter, you'll never know it, cause you'll never hear the shotJim or Paladin whichever you choose.
