Does anyone have a pic or can explain where they mounted their microswitch on the throttle body? I have mine kinda rigged up and it keeps moving, theres got to be a better place to put it. Where did you guys put yours?

 

I lot of people run jimmy-jams switch, and it's a nice piece. I just made my own out of sheet metal off there design.

the best place is in the throttle linkage. What you do it put it under the black cover where the throttle cable pulls the TB butterflies open. You take the microswitch and bend it into a U and put it under the plastic piece that covers the throttle linkage assembly and secure it using 2 small screws. You place it in such a way as when you go WOT the piece of metal that moves will touch the switch and close the circuit. I don't know if i have a pic, i'll look.

84 monte,

you have a pm.

 

Thats pretty nice, good link. I will be getting one.

 

A really easy and super clean looking install can be had when the switch is attached to the steering column under the dash. Just fab a simple bracket.

 

And how would that work?

 

I don't actually even use a bracket. I use wire ties through the holes in the switch to secure the micro switch to the steering column. Depending on your switch style, a simple "L" bracket may be required. Just go to the hardware store and buy some 1" x 1/8" aluminum strap, bend it up and drill some holes. I don't like running the switch at the throttle body.

I also just finished redoing my 68 Camaro the same way. Excellent, no wires up on the carbs.

 

Okay im confused. When the microswitch is put at the throttlebody it is activated when you hit the gas pedal, from that piece hitting the microswitch. On your set up what is hitting the switch to activate it at WOT? I dont see how anything on the steering column will activate the switch at WOT.

 

WTF?? I have never heard of anything like that. I have heard of people using the gas pedal to activate it and i thought that was crazy.

 

also just FYI NX makes a TPS switch that just goes off the voltage, no mechanical switch needed.

There's no need to swear fellas.

Typically, the gas pedal is located just to the right of the steering column. Mount the switch so the switch lever sticks out over the end of the pedal that comes at the driver as you actuate the pedal (usually the pedal is a fulcrum arm, it is on both my cars).

The steering column is just a convienient place to mount the switch. It gives you the variable depth to use as adjustment for hitting the end of the pedal at WOT only, or before WOT if ya got *****.

Again I don't like running wires on the engine, this setup puts the entire mess down where no one can see it. Pop off the under dash cover and I think you'll see what I'm talking about.

 

2 wires to a switch, i don't see where the mess in that is, but that is the beauty of doing it whatever way you think is trick!

 

I guess, to each his own. If you do it right the whole thing is covered by the black plastic throttle cover and like stated before it's only 2 wires besides what do you do with the wires from the noids, FPSS, window switch and relays? and I'm sure you've seen the mess o'wires GM put under the hood.

like i said earlier i've seen and heard of people using the gas pedal as the activation point. but in your first post you just said mount it on the column, you got to be more exact unless you are going to post pictures. people post to get answers not confused. not trying to be a pain in the butt, thats just me being me.

 

I did fail to explain the installation adequately.

When I pull the blower or perform maintenance wires just seem to get crushed or in the way. I'm mechanical that's what I like. When I do mechanic work electrical wires and devices are a necessary nuisance. Of corse, I'm the same guy who spent five hours and went through two sets of plug wires running them under the headers. But then the look is dynamite and top end work is easy and clean (68 Camaro). There are no wires on the engine except ground strap and plug wires, I even rewired the car from under the frame.

My LT1 is completely stock. I run a low pressure dry spray homemade nitrous system (and a homemade wet kit w/propane injection, not hidden, added later, still a work in progress). You will not find a single wire or feed hose leading you to believe there is a 150 hp dry kit on the car. Even when I show people the feed line they just don't understand. To me it's very important. The look is simple and concise.

This is what makes us all unique.

The solenoid is under the driver's seat (LT1).

The factory wiring is acceptable.

On the Camaro all the nitrous equipment except bottle is under the cowl panel, super, super, clean installation.

Getting back to the original post, the guy simply asked where did you put the microswitch; I answered.

I'll try to get some pictures this next weekend.
