I ended up not even hooking up the tan wire and the system works fine. I don't know if splicing into the tan wire is supposed to give you the ability to unlock the driver's door only and then both doors with a second push of the button...but I don't care. I traced both tan wires up to the glove box area and spliced into both since I couldn't determine which was which. Neither of them acted right and made the system just click. I never could fish the harness out of the kick panel. IMO, just splice into the the two wires (light blue & black) on the relay, the two 12v power wires, trunk release, ground it, and be done with it. Makes for a much easier install.
