send what back, you dont even know what tt he has????
im trying to help him out by giving the possible wiring. what is a load of bollocks about the wiring??? if he has the correct harness, the only wire he will have left is the handbrake light one. plugging in a harness and connecting one wire.
just because your plugged straight in and worked theres no need to give stupid input. his problem sounds like the problem i had, hence why im trying to advise to help him out.
