New harness fitted gone for round the frame although I thought it looked much tidier through the centre but as oddjob said possibly to make room for cables I would like to thank Big Al,Alan’s electrics  for making me the correct harness everything worked as it should and fitted perfect highly recommended

yes spot on only problem I had but nothing to do with the harness was it wouldn’t start when I had finished would turn over but just kept backfiring after many hours of scratching my head luckily I’ve got into the habit of taking loads of photos of what I’m doing before I touch anything I noticed on the coils the blue was connected to the yellow and yellow to blue swapped them round and started straight away I’m sure there’s some reason it was like that but not quite worked it out yet

Thanks for the feedback Simon concerning the new wire harness (1st/2nd images)  Much appreciated.

I gather the (4th image) was the original harness before you sent it to me?

Yes the harness in the fourth picture is the one which was fitted when I bought it I believe it either an f1 or f2 harness the bike originally had the wrong right hand switch fitted it had no kill switch on it I put the correct switch on but had to make it fit as you say the k3 has a block connector and not bullets there’s so many parts that are wrong on this bike and as trigg as pointed out to me it might of been easier to buy an f frame as I seem to have most of the bits for that

the harness I sent you was off my other k3 I bought as a doner bike depending on what I do with that one I might be after another one of your quality harnesses
