Mine is set up very similar to Greensleeves. I made mine so that by pulling out 2 hitch pins you can slide the rod out of the tail light and then pop a small rubber plug (I think it was a BISS plug) into the hole so that cops don't see a thing hanging out of your tail light and dicks don't fiddle with it when you're parked somewhere. In order to solve the problem of the car continuing to run when the switch is thrown, you can get a battery disconnect switch that has the two large terminals as well as two small ones on their own circuit. I run my fuel pump through the second set so that when the switch is thrown the large terminals disconnect the battery and the small ones disconnect the fuel pump thus killing the engine. It probably isn't NHRA legal but the end result is the same and the guys at tech inspection never questioned it.
