I bought the whole assembly from TNT motorsports here in Blaine MN, which means its probably mostly used for a carb set-up. The switch is normally open, until it is pressed then it is closed, Rated for 12v DC. the bracket says edlebrock and the switch says OTEHALL, England thats all I know about it. Worked great for a nitrous set-up but it is not a bolt on application it takes a little thinking to get it put on

 

just wonder if u got a exhust housing for the 16g?(HOT SIDE)

 

yeah, its the twin scroll exhaust housing up there
