Thanks Mark,
I can get the plastic flexible conduit and fittings, but my fear was that they would crack after a while. I spoke to a couple of auto electrical suppliers, and they both said that the plastic conduit would not last in that application. I suppose that I could do that temporarily to get the job done, another option is to see if I can find something suitable in a scrapyard.
I wonder what Tornado etc use?
regards
Dave
