i have a led rear brake light in my re spoiler and its not wired up. found a white block connector behind the plastic moulding at the front of the boot (nearest bumper). its 2 wires but a 4pin block. connected the led light in there and the light lit up nicely - but there was no brake lights on! wire it the other way around and nothing happened.
where would the brake light be for this as i presume the standard spoiler included a high level brake light?
TBH i dont think their was a spoiler with a high level brake light in it :S
I could be wrong but ive never seen one ?
as for the wire aint got a clue :D
your best bet is to get a friend to sit in the boot with a multi-meter in the connector
and you press everything you can on the dash ( and peddles ) and see if it gets voltage
this would give you a better idea
is it a jap or UK car ??
never mind .. it was the boot open interior light ;)
