I know this has been done to death but cant find the answer im looking for...
Basically, bought an 18 OBC of Fleabay and replaced it with my 8 OBC.
Only thing is, when i plug my black lead into the black spcket on the 18 OBC it does nothing! Not even light up or anythin!
I'm going to eventually get round to re-wiring the full white loom into the dash but though i could cheekily get away with just the clock for time being.
Is this normal for it not to work only on black loom or is the OBC DUFF???
