Taken from my old 748. It was working fine when I disconnected it about 3 years ago, so I would expect the backup battery is probably flat by now. All the wires are there to fit it to a 748/916/996 and the rear light has the little led fitted to it so you don't have to ruin the original one. It has two fobs, all the original paperwork and a spare magnet part for the seat sensor. Looking for £50 for it.
