i am currently stuck on the electircal work on my nitrous express wet shot kit, i was wondering how do you setup the relay.

This is wires from the Relay that comes with the kit.
Red wire is to the switch, but what do i send to the red wire? Positive or ground?
Also the black wire goes directly to the battery
Green is to the soleniods
And the white is to the fuel cutoff switch.

i tired to shoot positive and negative power to the red wire on the relay but my soleniods dont open and allow fuel/n2o to flow into the intake, what did i do wrong with my wiring?

 

I thought red was hot and black was ground

 

hey mann try this link i dont what kit u have but it should b on there
