For keys, if you are real cheap, could be made out of a metal coat hanger, it works but not as well. I'll look into the kit, the harness is $5, the kit with the AC wont be too bad. I'll see what I can get it for.
BTW the heater/vent control is attached to that unit, you will have to play with the knob to get it back on. I did one of them (ZX2) and it wasnt too bad.
