I have for sale the complete Cruise Control retrofit kit for a RHD drive car. This was sold as an accessory by BMW but is no longer available. Kit comes complete with all parts.
I bought this kit for my 1999 840, which had never had cruise. I managed to obtain a couple of missing parts to ensure it was all present, correct and OEM. Unfortunately, after much searching I have been unable to locate a particular connector on my car's wiring loom, which is essential for making the kit work. I can only presume that the very last models of our cars produced, did not have this in the wiring loom.
PM if interested.
