These were on Defenders though? The harness just isn't long enough to reach on a series. Thank you for the reply, good to hear that it is a worthwhile conversion. I just burned out my Lucas dip switch and my main light switch was getting hot so I reckon it's time to get this done, been threatening to do it for years...the ceramic h4 connectors on the Boomslang are removable using a terminal removal tool (or a small flat head screw driver)
the female spades come out of the h4 and it will then pass through headlight bowls no bother.
I've run into this issue doing mine and a mates boomslangs.
Worth while though.
I fitted one of these to my S3. As has been said, the ceramic plugs need dismantling to get through the bowls (auto correct tried to say bowel ). I don't recall having to extend any wiring.
Works well with new bowls, lamps and H4 bulbs. You can now, almost, see where you are going.
Me neither but it wasn't. I had to extend the wires by about 40cm to reach.I ended up cutting the rubber plug covers to open the holes up a bit, allowing disassembly of the ceramic plugs.
I'm still not sure why yours wasn't long enough ??
