I tried to retrofit cruise control to my 1999 2.8 Z3 with M52TU, since I believed it should work for that model simply by adding the interface module and the switch. I bought those, and put them on, but I can’t get the cruise control to work.
Now, there may be two possibilities:
1. The switch that I had bought, and which was supposed to be the right one (part number 61318360926) had an 8-pin connector, while the interface (65718380054) had a flat 6-pin connector. But since the switch looked right, and had the same amount of wires as the ones with 6-pin connector seem to do, I decided to try if it worked anyway, broke the connector and attached the wires together (they had same color codes, except one blue/green <-> blue.)
Maybe the switch was different, and does not work together with the interface after all? What do you think?
2. But, now I also noticed a post on this forum (on this thread https://zroadster.org/threads/retrofit-cruise-control.13617/) that apparently the cars made before 4/99 have “2 wire clutch switch”, which apparently is not a good thing. I don’t fully understand what it means, because both my English and my technical skills are not that good…
My car is made 2/99. So I guess the problem may also be that clutch switch thing.
So:
I quess I should first check which kind of clutch switch I have. How can I do that?
I appreciate any help, thanks!
