When you bypassed the CAGS did it kick any codes by not having the signal to the PCM? As I understand it you did not include any of the wiring in the harness so when to PCM was tuned for m6 there was an open pin on the PCM where the skip shift would have been. How did you alleviate any problems that this may have caused and is there any reason why you couldn't have just left the solenoid in place but not have it hooked up? Thanks

I removed it totally cause why have it there if it's completely useless.

I had the CAGS tuned out of the PCM when I had the M6 Tune put in. I wouldn't have any lights come on anyways cause the Gauge Wiring for the Shift Light isn't there either..lol

what did you use to de-pin the PCM and also are the cruise control switches for the clutch and brake the same switch ie same part number?

The PCM Connectors come apart..carefully take the colored plastic piece off and you can see the white Tabs that hold the Pins in. I popped up the Tabs and pulled the Pin out.

I don't know if the Switches are the same part number..I just moved the Cruise one over from the Brake to the Clutch and wired the TCC portion of the Brake Switch into it in Series circuit.

Since the TCC Function was no longer needed it was an extra switch..no sense of not using it.

I added a diagram to my first page..

I just did a t56 swap on my 00 Z28 as you, wired everything the way you did but the cruise switches, can I connect the TCC in series with the clutch cruise switch? What I want to know is if ls1 harness works the same as lt1 in this particular case?

thanks

Yes, it has to be connected in series, but wired like I did it in the diagram. The TCC Wiring will have no purpose if swapped to a M6.

Late respons lol

But, good info in this thread. I might be using this info for a future project.

Does the slave cylinder need to be drilled in a certin spot or as long as its close enough?

hey about the cruise control I have a 2000 trans am and this pic is how my wires are for the brakes and cruise switch on the auto side.

What do I do for this wiring?

or do I just take switch 25 and place it in the clutch spot and call it a day???? are any changes needed on the pcm wires for this to work? I know I saw it somewhere before but I can not find it now.

Hah glad to see this thread alive again I did this a few years back with the help of soome coaching by Merv. The only problem I ran into is that now my cruise control doesn't work. I have no idea how the swap changed that.
