There used to be general cruise control kits that involved strapping magnets to an axle with a pickup, tapping into a vacuum line and tapping into a brake light line. I have no idea if they still exist or if that would even work on a Metris.
Thank you. I have seen an installation on the Vito 447 as you said. The concern is if it can be programed on the US version and the part number for the control. I have encountered 2 different numbers. I had hoped someone has gone through the install. I do know that it has been done on the Sprinter without issue.
I am in the same situation. I have a Metris without cruise control. I have had no luck at the dealership or with any aftermarket units. Any and all details in getting this accomplished are appreciated.
