where did you get all your bits from mate ? obviously we don't have radio shack over here ... maybe maplins ?
Do you have a list of the UK bits and bobs you used ?

:Sport:
Yeah, it was Maplins. To be honest they weren't that much use. You need a 0.250" female 'Flag' terminal to fit in the headlight plug - they don't do one. I modified a straight 250 terminal by flattening out & trimming the crimp & soldering the wire to it at 90 degrees. A bit of trial & erroe required, fortunately, I got it right first time. However, if you can get a Flag terminal, it saves a whole lot of pissing about.
The wire Maplin's sell by the metre, I just asked for something that would handle 12 Volts X 65 Watts. The wire supplied, IMHO, was a bit chunky compared to the stuff Yamaha use anyway. You need about 1.2m of cable, if you are going to run it 'tidy' around the front of the fairing & connect to the feed wire by the handle bar switch. I bought green cable at first, when I fitted it I thought it looked wrong. So, I nipped down to the local car parts dealer & got a reel of black wire for a couple of quid. I think it looks less obtrusive & is easier to hide as you wind it round the harness.
Black cable ties (zip ties), again a bit chunky for the job but the smallest they do is about 150mm.
Black heat shrink. It depends if you decide to cut the green/orange dot wire when splicing the feed, if you need heatshrink or not. Obviously, if you don't cut the wire, you can't feed the heatshrink tube over it. I bought the heat shrink, then decided not to cut the wire, just stripped back the insulation & soldered the feed wire to it. I used green insulation tape as I already had it.
I then used black insulation tape to bind the harness. It's a bugger to do it tidy, but possible if you're patient. I know somewhere in this thread waterproof insulating tape is mentioned, I think that must be an American thing, not something I've encountered.
Most of what I used, you should be able to get at a decent DIY car parts store. If you've got one nearby that does in-car audio, that might be the best bet. The electrical wholesalers by me where useless.
I spent ages trying to find the other end of the green wire to no avail. It disappears into the frame below the battery. Obviously, if that were accessible it would be the place to connect the feed wire to.
Hope that helps, give me a shout if you need any more details. :thumbup:
