That's true. If your bass has normal plastic coated wires, there's no reason why it couldn't be a genuine American Fender.
If you want to buy a new wiring kit, there are a few guys on the forum here who'd be more than happy to make you one (check the Affiliates forum for more info). You could, of course, buy one from a parts website, however the P/J VVT configuration might be a slightly harder layout to find.
