Perhaps it has been sold as something it isn't on e-bay? I had to send back a main stand because of that, but on this topic I bought a clutch switch of e-bay and just about had to
squeeze it in. I've got a David Silver loom also, and no the colours didn't match the male plugs on the switch cable. I tried the
suck and see method but the plugs were stripped from the wires as soon as I pulled them out and not like I was forcing that part of it. I guess it was made in China. I'll try a DSS one next time maybe, but I'll ask
him what the colours are for his loom and switch wires.
