Hey guys, I want to install the smoke switch on my common rail so I can blind the tailgating prius driving hippies. I've read alot about it on here, and I'm still not sure about wiring it correctly. Most of the posts I've seen say that the two wires that need to be connected to the switch are C and D on the MAP sensor connector. Just being curious I looked at a wiring diagram, and noticed that C is a 5V supply, and D is a 5V supply, and I cannot for the life of me see how connecting two 5V supplies will do anything. It seems to me that pin A and pin D would need to be connected, as pin A is the MAP sensor signal. Can anyone explain this electrically and tell me if I'm thinking incorrectly. Thanks.
