Hi there! Forgive the message, but it looks like you had managed to successfully wire up a 987 rear speaker shelf into your 986. I just bought one and I'm wondering if you have any info about how you wired yours? I'm guessing I'll need to splice into the connector that comes with the shelf, and splice that into the exisiting wiring for my aftermarket double din head unit. Any advice you have would be awesome, I think my biggest struggle is going to be knowing which wire is what on the shelf end.
