I have 2 wires coming from the kickdown switch on my '70 w/TH-400: 1-orange and 1-black w/purple stripe. The orange goes to the connector on the side of the trans, but the b/ppl is not hooked up. It has a connector on it and I know it needs to feed 12V to the switch, but I can't figure out where it hooks up. Neither my assembly or service manual shows this. Anybody know? Thanks!!!
