I cant remember what wires are which colour for the bulb, ask on migweb.
But basically there should be a plug, you just put a bulb between the two pins on it, it should come on solid when you turn the ignition on and go off when you start the engine if its working normally.
Then there is another plug that you short two pins on to get it to flash the codes.

No point anyone guessing at anything till you have flashed the codes out of it.
