The earth on the light cluster should be common so you should be able to trace it to each bulb in turn and then into the wiring connecter. The + side for each bulb should go into it's own connection on the connecter so should be easy to tell them appart. Failing that an electrical tester will be the key to finding the earth (or a bulb with 2 wires connected to it if no tester is to hand). Turn on your car lights to light up the bulb in the cluster, then remove it. Connect one side of the tester to an earth on the chassie and then touch each conntact in the blulb, if the tester reads voltage (or bulb lights) that's the + if not thats the - (earth) should make it easier to trace back to the connecter then. Once there try again just to make sure you've picked up the right one.

Sure there is an easier way and hopefuly a auto spark would be able to tell you but that method should get you going.

Hope this all makes sense mate.

I know which socket in the connector is the earth. I used the wiring diagram in the haynes manual, lol.

I'm just wondering how bob connected the earth cable that he put going to the car, to the cluster as they are Crimped pins if you get what i mean?
