I have found a 5v source (5.35v to be exact), although i am not sure what its for.
It comes on and goes off with the key (ACC position) and does not alter when i turn on anything in the car, lights, wipers etc..
(It drops to 5.15v when the car is running)
So hopefully that will be ok to use. If not could i simply use a 1A 5v voltage regulator to drop it to 5v?
OP
