its already installed, i got the wiring harness from MSD, but my mechanic said that to get the window switch working i need some other parts but he didnt tell me. He also told me that i really dont want to run the window switch cause the micro switch on the TB is a better safegard because all you have to do is let off the gas and the nitrous is done. I know that what he said is BS thats why i'm taking my car to another guy that is going to look over his work and i want to get the window switch working. So is there anything else i need to get for the window switch working or was the mechanic just blowing smoke up my ***?
thanks for that help

 

Nope, Nothing else is needed.
All the window switch is a ground signal when the rpm is between the settings you have.
I hooked mine through the FPSS and then to the ground side (85) of the relay.
