viper 5701 in 2006 mustang gt problems

In the nicest possible way, and no reflection on you because hands up those of us who HAVEN'T boxed everything up to find something silly not working, I'm just patting myself on the back when I say "I TOLD YOU SO"! At the end of the day, my face is as dirty as my hands from looking up into the dash to either mount things or check plugs. Heater controls on Toyota Supras and Mazda RX8s are prime candidates. You should hear a slight click as the plug locks home.
