could have taken it from the sidelight before the bulb. its what i used to use before the gizmo.

also with DC electrics you dont need a 'ground' (negative) fixing. you just need to create a 'daisy chain' on the live. its only when attaching direct to the battery you need to attach a negative. cut the feed wire and put the positive on the feed end and the negative on the other end of the wire.
