HELP!!! wiring JTech switches
I am in the middle of trying to wire my new Jtech switch housings. I tried to make it easier and reuse the old switch housing wiring harness. I cut them as close as I can to the old housing and I also have a burly extension kit for my 14in Apes. I have folloed the wiring diagram on Jtechs website but the Hi/low beam wiring is confusing me. It says I need a relay but how do you wire up a relay and where do you mount it so I can hide it? I have attached the pictures below, any help would be greatly appreciated. I am new a electrical work.
This is the new switch unit
This is the old harness with the horn and turn signal switches already wired up. As you can see I have 2 wires coming off the new switch unit, a blue and gray. I have 3 wires left on the old harness a blue, yellow and white.
This is the right side switch unit, I have everything wired up here as well but I still have 3 wires left too, I as pretty sure they for the rear brake light switch. I am ordering a hydraulic pressure switch to replace that one so I will use at least 2 of those wires.
