I should have know better but after I got no worky, I figured it out. Also, they could have made the note that it comes pre-programmed for the Alpine functions a little larger and easier to read. I caught that detail but I can imagine someone could gloss right over that.

thanks kev, the pac instructs arent the best but the owner of the shop has a separate set of wiring instructs that are perfect so it was easy. the tr-7 is already programed from the factory to work on alpine so thats cool. i think i know where the problem lies but im too lazy to try the tr7 again, plus my harness wires are getting short.

since the parking wire on the tr7 only puts out -150mv, i dont think it is enough for the alpine to sense it. when i hook the alpine parking wire to chassis ground, it works like a charm. as it says on the tr7 instrucs, there is only -150mv comming off the parking wire.
