Glad to hear you have a method you like to mount your Rostra (wow, that just sounds nasty).
As far as the wiring goes, it is the same on all models of C-14 across all years, as far as the NSS wire in the top / left rubber boot goes (the only thing you need to connect in that area). The wire you want is black- mine had white dots along its length but the schematic shows the wire to be black. Now if you turn the connector around, the SAME CIRCUIT changes wire color to Red w/ Green stripe.... but it is the same circuit, in the same position in the same connector. Use either wire, it does not matter but the one that appears facing toward the rear, and hence the easiest one to get to, is the black one.

I am looking forward to completing this. I just got some additional information from FartyMarty. I really like his mounting location. No fabrication and trying to massage body panels. The information available is finally starting to make sense to me. The wiring harness under the left dash is not the same as the 08 model. A smarter person than me figured out which wire is the correct wire to hook the clutch wire to and posted the diagram. . Looks like the only fabrication required now is a bracket the control cable.
