I have recently installed a 1999 4.0 into my 1990 XJ. Ive gotten most everything hooked but the TPS and am curious if i can wire the new style TPS onto the the old harness. Any help or advice you have will be greatly appreciated.

They both have three wires going to them. Is this something you have done or seen done? Thanks

each of the tps's use three wires, a ground, a reference(.5 volts from computer), and an output wire all you would have to do(i think) would be re wire them to where the specific wires match up ill do a little home work to let you know which is which

You cannot use a late TPS on a Renix (87 - 90) - it will not work. You need to adapt the early TPS to the HO throttle body. There are several ways to do it and several write UPs on installing a 91+ motor in early XJ's The Renix computer is not compatible with the late OBDII equipment!
