The question is... Does it work? Well, after fighting Forscan for a few hours (seems it doesn't necessarily like programming firmwares in devices that didn't come out of your car - I had to revert some saved config files to get firmware programming back!)... Yes, it does work:
I stuck a slightly better [glare wise] picture in there. And yeah, that Cluster is made up from spare parts from a Terry SZ, a Mk1 G6E and a Mk1 5.0 FPV... All the really good stuff ended up in my car, but I had enough nice stuff left over to make a spare MKII Cluster
