After reading Jamie's excellent instructions http://www.z4-forum.com/forum/viewtopic.php?f=32&t=19242 in combination with the official BMW instructions I thought I would give the retrofit cruise a go.
I have followed all Jamie's instructiions step by step and have checked all wires are going to the right places, taking note to ignore the official BMW instructions to route to pin 4 in the 26 pin plug. Mine goes to pin 39 in the 42 pin plug in the DME control unit.
The only thing that I didn't do was to use the repair cable as the pin on the end of the black repair cable looks identical to the pin on the end of the long blue wire. I believe other people have had success not using the repair wire.
Anyone have any ideas? If my crimp connections were not done properly, would anything on the car not work, because all seems fine apart from the cruise not working.
