what is this? stereo wiring question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

>X< · 12-23-2002, 04:50 PM

yeah, well i had a urge to do some work on truck today, so i finished shaving front side markers, started on back ones, took ot glovebox and took out crappy tape player (see other post about friggin dash) because i'm about t do something to dash, dont realy know what yet though.

BUt anyway, i was labeling the wires for the stereo and i am stumped. theres are two wires that go from back of stereo, spliced n to speaker wire, then split apart again, one goes t fusebox luster of wires and one goes to this thing that is near my gas pedal. when you push the pedal in it hits this plastic thing that either cuts off or gives elec. to this wire, that goes back to stereo. what the hell is this? a volume control, maybe turns it up? i never ad any speakers in so i dont know what it does, radio does work though. an thoughts? i took soem pictures but they came outbad so i'll get some more in a minute. thanks, sean

here's a picture of he switch. only one of the metal things had a wire connected to it, the brown piece of plastic moves in and out, the rubber was the guys way of adjusting it, the rbber piece is what the top of the pedal hits to move the brown piece

Do you have any better pics? It looks to me like the kick down swich for a pontiac. I have one, if you get A better pic I'll compare them.

its a gas pedal mounted kickdown for a th400 stock on 72s

what is a kickdown switch? why does it go to the stereo? my guess is that it turns the radio louder with throttle, but i guess it doesnt work. i'll get a pic wtih it installed tomorrow

if i was at my house i wuld take a pic, its in a bracket that has to be stock, you cant take the bracket of, it holds the pedal on. do yall think i should take it off or leave it? i'm trying to get rid of junk wires and kinda replace the important stuff

That switch is for a th400. That is the electronic passing gear switch. I dont know why it is running through the stereo wiring harness.
I hope this helps
