Michael, the tacho is the easiest one to start with. The Mk2 clocks want the signal from coil negative, and a 20v on coil packs hasn't got one, so you need the tach output pin from the engine ECU or that converter you have. Check which ECU it is running and look up its pinout for the rev counter wire. The speedo depends on the gearbox. If it is still a cable box the cable just needs to reach, but a later box with an electronic sender needs a pulse to cable converter or electronic clocks. On the fuel cell, a simple float switch will only ever give you a low fuel warning and not a proper gauge reading. For the MFA oil temp you need the correct sender, normally in the oil filter housing, with its wire run back to the clocks.
