I have a 2005 dodge cummins 5.9L and I want to put in a smoke switch can anyone tell me what wires to use I have found the MAP sensor can anyone tell me if C is the power wire and D is the negative or vice versa?

 

You probably won't get many positive responses to your question here. The reason being is that the site basically caters to performance enthusiasts, and people who want to improve and maintain their trucks. Excessive smoke, especially for no reason frowned upon in large part because it usually is a sign of a truck that isn't set up well or someone wanting to be, and I don't want to sound unkind, obnoxious, which draws the wrong kind of attention.
A truck that sounds good, runs hard, and can burn the fuel being given to it, now that's impressive. A properly built truck with a turbo and injectors that are well matched and a good tuner should clean up pretty quickly under hard throttle.

Yea be carful about a smoke switch on hear. Have read a few threads on hear and guys get tore up pretty bad about wanting one. I would just build for power and the smoke would come.
