Bad luck for me, the seller didn't agree to sell to anyone outside North America. Hope another one will appear...

Hello,


I have been doing the same thing with my car.. it has the same features with your car and I bought the necessary cruise control parts from e-bay.. which are:

1-cruise control pump(vacuum motor)
2-turn signal arm with cruise switch
3-cruise control relay
4-vacuum modulator
5-plastic piping required to connect the system.

my system didnt work too.the car has Lh jetronic fuel system with ez129 k ignition control module. the car is auto so it has a tcu control module too.


when I removed the steering wheel upper cover to instal turn signal arm with cruise I saw a white connector which was pre installed for use with turn signal arm with cruise this made me think that the car was factory prepared for later installation of cruise control kit.

also in the fuse box module in the engine bay, when I removed the fuse box cover which has 4 screws I saw the place for cruise control relay is also ready too.

however I was unable to make the cruise module work until now..


the possibilities are

bad cruise control relay, bad turn signal switch or a bad vacuum motor. or the last possibility is the car is incompatible with cruise but this is doubtful because if it is incompatible why the wiring for the system was made in the factory?

so we will work and see what happens..
