Just fitted mine there. The H4-3 kit must be wired differently to the H7. On mine there was 2 black circle connector wires (one for each bulb) which have to be connected to ground (bare metal on the chassis) and a red one which is connected to the +ve terminal of the battery. Couldn't get mine to work at first, but I realised I hadn't connected the two ground wires correctly to the chassis. Might need to get self tappers to get them screwed on.
