do i need a relay?

I just recently got my 280c 150psi hi flow air system for a horn i built. Do i need to wire a relay in or not? Thanks guys

 

Bump. Quick response would be very helpful.

 

yes

 

Thank you. Do you know of a diagram of how to do it?

 

I also have a switch that is rated at 3A 250v switch. Will that work with my compressor

 

a relay is just a remotely operated switch. it takes the load so you do not have to run heavy wires in and out of the truck. 86 and 85 are used to trigger the relay. positive and ground are run to 85 and 86. postive to one ground to the other does not matter which is which. 30 is input power. wire from your battery. 87 is output from relays. the pins 85 and 86 connect pins 30 and 87
