For MK2 clusters, a 1.3 8v speedo for 02A/02J gearboxes. Without looking at the ECU logic, I do vaguely recall you still need an electronic speed signal back to the ECU. Hence the reason most run a MK3 cluster.
if its a coilpack engine you can use diodes hooked to 2 of the spark triggers inside the coilpack: http://www.clubgti.com/showthread.php?98913 if its a distributor engine then you'll need adaptor(s) to convert the ecu signal from 6 cylinder to 4 cylinder, then change it to the negative pulse that the MK2 clocks expect
aye was just assumed that a working rev counter was also required even though it wasn't mentioned for the ECU speed signal feed you would need GTI clocks or swap a speed sender from a set to the ones you have, sometimes they have the ribbon to retrofit it but not always. Wiring wise it depends what fusebox the car has, CE1 its fed from a spade wire hanging out the bottom of the clock plugs but this isnt always fitted. CE2 its from W/1 on the fusebox, usually there is a wire here but again not always. if you look at the radio often there is a white/yellow wire which is the VSS feed you need, since most stereo dont use it you can pinch it for use with the ecu
