This isn't going to be something that METRA would make. I'm not looking for the HU wiring harness but rather one of the wiring harnesses in the trunk that connect to the factory Monsoon amp. It should be very hard to find.
Should be a Metra 70-1784 harness. I asked about the Monsoon because it like most amplfied VW systems is speaker level input. The thing about the monsoon is that it's a current sensing turn on, so it doesn't need a remote turn on lead.
