Hi guys! I have just purchased a spot light kit for my 5.1 for the money it looks a decent set to be fair! I have the two lights and a set of led lamps plus the wiring harness. My Question is I have a main feed and Earth plus a relay with a blue cable and another earth. Main connection I assume go to battery but where would you pick the sw live to relay from? The loom is fairly short? Also there is no screws to fix the lights back anyone have any idea what size screws are best to use? Thanks Guys
