I installed a new Kenwood HU (http://www.crutchfield.com/cgi-bin/S-9ApsNhyAbG8/ProdView.asp?a=0&s=0&g=300&id=other_items&i=113KDC2019) into my '98 Mustang last night. The Rio will be plugged into the HU via a cd changer -> Aux adapter (also shown in the above link).

I was planning on splicing the rio's power cables into the HU's wire harness, but I'm wondering which cable is the actual power. I'm guessing it's "Ignition Sense", but just want to make sure before I start cuttin...
