The first step is deciding where to put the solenoid. I went with Wrangler's 200Amp continuous duty solenoid but its mounting orientation, I thought, was kinda limiting. I decided that the best place to affix this would be between the two horns on that metal bracket that they are connected to. Now the spacing between the solenoid is just slightly too narrow so you will have to widen it slightly. Again, this is only if you are mounting it here. I wanted it out of the way and more or less hidden so this made sense for me.
Once there you have a small power post and a small ground post. It doesn't matter which you use as ground and which you use as power. I used the mounting bracket as the ground. Just a small piece of wire with an eyelet connector and shrink tubing on both ends.
The power wire will need to be longer. You COULD mount the switch near the quick disconnect or even in the engine bay but this didn't make sense to me because I wanted to use the cables without having to lift the hood. Plus I didn't want random people flicking my switches if its exposed. So for me that meant bringing it into the cab.
I had already bought an extra hazard switch and had figured out
how to relabel a switch thanks to another mud member who I don't remember made the mention.
From there I just made a new label and installed the switch. I was able to figure out which wires I needed to connect in order to complete the circuit so I brought the wire from the solenoid and connected it to the switch. From the switch I connected it to my new aux. fuse panel with a 5A fuse.
The switch in the dash now turns the solenoid off/on to allow or not allow current through.
