I've been looking around for adapter to solve the hyperflash issue with trailers equipped with LED. Apparently is back ordered everywhere.

I did find an alternative that requires going over to the competition: VW has it in stock because their Touareg has the same problem... At least they are nice enough to acknowledge the issue, put out a TSB and stock an adapter (which is nothing more than what Valley offers, rebranded).

Here's the TSB from VW with the part numbers: VW TB 94 06 15

So worst come to worst, put your pride aside () call up the VW dealer and ask them for that part...
