Hi guys,

This question isn't PURELY jaguar-related, but its 50%!

I swapped my XJ6 engine out a couple years ago, and replaced it with a 1994 LT1 from a z28 Camaro. More recently, I replaced the 4l60e automatic with a T56 manual. I've been trying to get my cruise control to work. I bought a new bellows, because my old one was pretty trashed. I've also relocated it slightly higher, in order to get the new bellows away from the hot exhaust headers.

I'm not entirely sure how the new set up would work -- since my cruise control never worked on my original motor (the previous owner had messed with a bunch of wires), I'm not sure exactly how the cruise control is set up. Do the bellows actually pull on the throttle? Or do the bellows hold the gas pedal in place? With the LT1, I don't use the Jag ECU at all -- but i still have the cruise control computer (the one under the passenger side footwell). I'm not sure of what I have to do to get the system to work. Any ideas?

 

I have taken out the cruise control out of every car I had... From what I remember, the XJSs had that bellow compress with vacuum, which would pull the accelerator wheel/tps at the pedestal. There is a vacuum switch opening/closing/modulating.
