I bought a Nitrouse oxide systems unit off of e-bay used and it does not have any instructions on wireing up the relay it is a four wire relay orange wire is fused hot wire but it has a green wire a red wire and a blue wire If anybody has one of these units please help me on the wireing. Until then I will be playing with the electrical meter.
Thanks Tpsycho

 

I would take it out next to your battery and connect the fused wire to positive then try connecting the green to ground and then touch the other two wires together as these other two wires will probably be the handlebar switch. You should hear the solenoid activate when you touch the other two wires together.

 

You did get the solenoid with this didnt you?

 

Yes the cube relay came with the setup if what you say works that means I should have another output coming off of the relay to the fuel and nos cylinoids ?

Thanks for all the help found that the red wire activated the cylinoid when power is applied to it and sends voltage to the nytrose and fuel cylinoids thrue the blue wire.
Thanks again for your help.
