is that the switch near the fuse box in the cabin? or near it? or under the steering column.

its on the clutch pedal. the worry isn't that you will have a mishap its when you have it somewhere and a valet jumps in and starts it or a tech at a shop. american cars and drivers are trained that cars won't start when in gear and when you bypass this they aren't prepared for it
its easily reversible. you don't even have to remove the switch just disconnect the wires and jump them

thx steve i have a no valet policy. btw the cars and whoever is with me on any given sat nite haters gonna hate, and my tech is my bud and it is rarely if ever in a proper shop. but i'd warn them. i'm in a good spot to pull this off with no downside, and if it saves my thrust bearing? or accumulator since i'm still stupidly running the oem clutch setup, then i think it's a win win.

disconnect and jump em.. piece of cake, got it. again, thanks.

It is simple enough to remove the clutch switch but still make it safe... Just add a momentary-on switch that like a "Start" switch that would replace the clutch switch. Then there is no chance of starting the car in gear "by accident" because needing to push the "start" button will remind you of the procedure and stop anyone who does not know the procedure from starting the car at all.

Does the DME use that switch for anything? I'm betting that standalone guys use it for 2-step etc.. A momentary switch is a good idea to leave the switch hooked up but bypass at start. Actually, I'm pretty sure cruise control uses it! Mine isn't returning the whole way so I'll check it, I've got a code set. Anything else? Does the ECU retard timing for shifts?

An anecdote... In my state it's illegal to have a remote start done on a stick shift car I'm told. Several shops I've talked to who had done this install for customers who swore they "never forget" have told me that every single time the customer has had an instance of an "accident"!

A momentary switch is an awesome idea to have the best of both worlds!

I can't imagine there is actually a law for that. I can see a shop deciding. Not to do it for fear of liability and then through communication to subordinate employees it is thought to be "illegal".

It's a wonder anyone made it to the age we are at given all the dangers we pose to ourselves!!! Lol

seems reasonable enough and a good compromise? but isn't that going to require some jerry-rigging of a toggle switch somewhere? i'd really like to avoid all that too!

as others have just noted, it probably is an infraction given the govt.'s need to protect us from ourselves

proefi 2 step uses the front speed sensors to disengage the 2 step. clutch in, stand on the throttle. rpms go to 4500 and timing cut starts as does boost building. mine is set at 7 psi. when you dump the clutch and the front speed sensor reads 1 mph (thats were mine is set) then the 2 step disengages and you have the full rpm limit in every gear forward

I removed the clutch spring and have the gt2 slave setup and modulation is 100x better. Love it!

Checked mine, with the top cruise switch not engaging it won't start so there must be a second switch.

Makes sense on the ProEFI, I'm so used to other cars not having access to ABS sensors. Much better way to do it than relying on a clutch switch.

i finally did it! twisted the wires and inserted a fuse in btw two ends that complete the circuit as a failsafe to not shorting anything out!

now i cant stop pressing the clutch when i go to start the car! LOL

even though i no longer HAVE TO! argh
next up: spring removal and slave removal. though that one can wait $$$

crappy clutch =crappy feel. when you upgrade to a carbonetics or erp you feel the difference. i have had both clutches and new they are like a lightswitch for engagement. after a 1000 miles or so its like butter

I am at a loss. Upon clutch spring removal (love the new feel) the cruise will not operate (no green indication in display upon pressing button on stalk). I examined underneath and did notice the clutch no longer engages the plunger so I removed the plunger spring and taped the plunger so the contacts were engaged. Still no cruise. Any thoughts?

Pull upwards on the clutch pedal with your foot while driving, cruise engage? It should and will probably disengage as soon as you stop pulling it up. In my case the gap is pretty narrow and I'll probably glue a small pencil eraser to the plunger to make up for it. Haven't needed cruise,though since I did this and thus haven't done it but I know pulling up works on mine...
