Right, Iv got a bit of a problem with my ABS, Which is the Late MK3>Mk4 type (the one with the pump and ecu togeather). I installed this In to my MK2 when i was putting in my G60 (seemed like a good idea at the time). Any-how its all in but it just doesnt work. I have already tested the loom and it checks out ok. On this unit there is a single diagnostic wire (grey/white). I have a OBD unit with both types of cable (black and greay 2pin & 16pin OBD II connector). Using the black & grey plugs i powerd up the obd and then pluged the grey/white plug in to one of the grey plug pins. Ran the diagnostic and nothing. So i tried the other and also nothing. Both tests were done with the ignition on (engine not running). Any one know if i wired the diagnostic lead in correctly?
