I recently put Kingsborne wires on my 400E. It's sounds like an offbrand but all the fittings are made by Beru which is OEM. They are made in California. Workmanship was excellent, lengths all perfect, wires numbered, etc. As I recall price was a little lower but not a lot. I think a search for Kingsborne would find them. I believe they sell direct and also through dealers.
