hey ive had the swap done for about a month and everything works good, had it tuned but my cruise control doesnt work and i have a check engine light code that keeps comming on, its clutch pedal position sensor. which is the switch that goes on top of the clutch pedal that disables the cruise when you hit the clutch i never added it because everyone said theres one on the brake also so i dont need it well i never put it in. so now my cruise control doesnt work and i keep getting this code, is the reason my cruise doesnt work because i dont have that switch? also can i have my tuner tune it out so i get no more code and my cruise can works again?
heres a pic of the switch

thanks

I can't see the pic(blocked here), but I'm willing to bet since the LS1 Cars have all that wiring in the Harness and it goes to the PCM, that may be a factor.

I have a LT1 Car and the Cruise is on it's own seperate Circuits, so I don't see it being a problem for me, I didn't wire it on the Clutch Petal.

Yes, you need that for the cruise control to work.

It may be a seperate Pin for the PCM to sense it..one of them things that you have to have there. I wonder if it's something that can be looped on the PCM Connector, as in you won't have to re-wire the whole Harness for it.

of the four wires one is a pcm connection that comes from the foot well on the passengers side if you swaped engine harnesses it will be on your new harness connector, if not youll have to run it to the pcm, two of the other wires are the circuit for the cruise signal and diengagement, and one is a ground.

can it be tuned out?

No you cant tune it out, you have to do what was stated above ^^^

That's the one I was referring too, I wonder if it can be looped somehow in the Harness and made to where the PCM senses it as being a closed circuit all the time..

Thats the clutch pedal anticipation switch.
I'll get some pics of both ( I think I have them)

I ran a wire to the computer when I did my swap. Just one for the cruise, but this switch does more than disengage cruise, it has some effect on idle down too.

Heres the A4 set up for reference.


Heres the M6 set up.


This is the black with w/white stripe from the clutch pedal anticipation switch (or clutch pedal position switch(CPP)


You need to find the wiring harness in the pic with the M6 switches. I got mine from a pick your part junkyard, V6 or V8 doesn't matter, not sure about the years. You also need to get a good length of the Black/white stripe wire and gray wire out of the harness and cut it off.
Then remove the small wiring harness from the small switch on the brake pedal, it has two wires, pink and black.

The small M6 wiring harness has the same pink and black wires in it. Plug the big end of the wire harness into the switch in your pic. Plug the small end you removed from the A4 harness into the small connector with the pink and black wires. (this comes out of your existing chassis harness.)

Now what you should have left over is a gray wire and a black /white striped wire.
Splice the black/white striped wire to the black/white striped wire on the ALDL connector.

Now run the gray wire to the engine computer pin 32 C1 Blue.
You'll need to get a pin either from an unused A4 wire or a donor car.
I tried geting the whole wire from a car with no interior, damn near impossible without cutting it.

Hope this makes sense and helps.

i went to my tuner today and he tuned it out and it has not come on again i drove atleast 100 miles today it usallly came back after 5 but my cruise still dosent work anyone know why

Hey 9000th.. is all that stuff you listed just for the Cruise on the LS1 Cars?

I ask cause I know mine on my LT1 Car is a seperate System, and it worked fine now as an Auto after my LSX Swap, so I see no reason why it shouldn't work for my T56 Swap.

Mainly for cruise, but there are references in HP Tuners about the clutch pedal position so I'm assuming that extra wiring harness and switch that activates as soon as the clutch pedal moves does other things than just turn cruise off.

K. I'll have to see how my car does with not having it..

Hey Robman, how is your car driving besides no cruise? Does the RPM's and stuff like that drop like that when you shift? You have it tuned for the T56, right?

yea i have it tuned and it drives ****** great besides no cruise and i dont have reverse lockout wiried up yet thats a pain other wise it drives perfect i love it. and i had the wiring diagram printed out for me about that sensor and its just for cruise i had my tuner tune it out and its all good no more code the cruise still doesnt work but i could care less anymore

Ah..that's good to hear. On the LT1 Cars the Cruise is on a seperate circuit, so mine will still work. I just didn't wire the Clutch Petal in.

Here is a diagram of the Pedal Switches I found..




On the 1999 up LS1 Cars there is that one Switch there with the 4-Pin Connector. I don't know how to wire it in, but I'm sure that one of them is a power wire, and a couple of them go to the PCM.

The reason I labeled the Torque Convertor Connector is because there are 2 wires there that can be used. One of them is a power, and the other goes to the PCM, well if you have a M6 Harness this wont be in it, but it goes to them Connectors under the Passenger's Dash on the car..
