Possibly, but it didn't seem like madness at the time.
I read loads of threads on here on HID kits and several people seemed to have used the HIDS4U kit and spoke well of it. For something like this with electrical components (especially high-voltage electrical), and being my most significant mod to date (!) and lacking experience at this sort of thing, I personally preferred to buy from an established UK-based retailer rather than an eBayer who for all I know could have disappeared by tomorrow (not saying that all eBayers are like this of course, but it does happen). Just stating my own preference at that instance, I'm not saying anything bad off eBay and buy loads of stuff myself off there.
I can only guess that the connectors in the kits had been changed fairly recently because no-one else had reported a problem with the connectors in the past, as far as I could tell. The modification was very easy to do and took just a couple of minutes with a hacksaw, and they fit perfectly now, it's not a bodge job. I could have dispensed with the cutting but would have had to compromise on where I wanted to put the passenger side ballast unit.
I also learned quite a lot from doing it and increased my own confidence at being able to do a bit of fiddling around and come up with a nicely-installed (IMHO) solution that works well.
