Default Cruise Control not working after T56 Swap...

Hi guys,

I'm trying to get Cruise Control working in my T56 inspired Jag Xj6. I have wired up the system based on the diagram below:

http://dl.dropbox.com/u/24984984/GM%...0XJS%20(1).pdf

This set up worked for an A4 setup, but I'm having trouble getting it to work with my new T56 setup. For my T56 setup, I haven't added the second in-line switch for the brake pedal, but I figured for testing purposes it should be essentially the same as having one switch, as the clutch anticipate release switch functions as a normally closed circuit, until the pedal is depressed just like the primary brake switch.

Here's the wiring diagram I used to confirm the correct connections in my vehicle:

since the system worked on an automatic, perhaps it is a tuning issue? or is there another additional switch that I am not taking into account? My current set up does not have a clutch "saftey" switch, ie having to start the car with the clutch down, although I don't think that should matter either, right?

Any help?

I think the speed sensor reluctor on the t56 has a different tooth count than the auto. So yeah, it could need a t56 flash in the pcm. Is the speedo reporting correctly?

I know this is old, but I have a similar issue with my 2002 vette. I swapped from auto to manual, appears to be wired correctly. When I set the cruise it will say it is engaged for a second, then says cruise control disengaged. Here is a link that I wired to.
