Cayman rear lid release cable - where is it?

[DoctorJ]

I'm at a complete loss on how to open the rear deck lid! Battery went dead in my '07 S, tried the positive post in the fuse box without any luck. Read somewhere that there is an emergency release cable in the left rear wheel well, but can't find it there (rear part of the inner lining is riveted to the heat shield - which I don't want to drill out unless ABSOULTELY necessary). Also found a thread saying you can get to this cable by slithering through the inside over the top of the engine and removing the rear tail light on the left side. But, I DON'T FIT back there.

Anybody have actual experience with this issue?

Thanks in advance!!
