Wiring help

So I picked up a set of Morimoto 4bangers for my 3rd gen and I was asking morimoto what the wiring diagram is to wire up a Cali raised switch. They emailed me back this. The only wire I'm confused on is the blue "trigger" wire. Could anyone explain to me what that wire is and if I need to wire it up? Not to good with electric stuff so I'm learning as I go. I appreciate the help anyone has to offer!

 

Typically trigger is the output of the switch that goes to a relay to trigger it (turn it on). This trigger is for low current to just switch the relay on. The heavy load to your accessory is then carried completely by the relay and not your little switch.

 

Thank ya for the advice! I managed to get it figured out.

 

So if anyone's looking in the future for wiring up the Morimoto 4bangers to a Cali raised switch this is what I got Goin tonight.

The 3 wires coming off the harness of the 4 bangers switch it comes with is a yellow, brown, and blue wire.

Yellow to black
Brown to green
Blue to the two reds
