Jeep Power Relay System

Jurassic Jeeps have a lot of accessory devices requiring 12V power, and my battery terminals were getting crowded between the OEM starter and fuse box cables, plus the winch and battery maintainer connections. Not a sponsored link, but I added this MICTUNING Wireless Switch Panel to add some more controllable circuits. I liked the wireless controller for easier integration, and I had an idea of using it to remotely trigger dinosaur sounds, but I went a different route for that aspect, which I’ll share in a later blog.

The Jeep engine bay isn’t very crowded, but I couldn’t find a large enough spot I liked for the switch panel, so I made this bracket in SolidWorks, which anchors to the 3/8” rods supporting the front grill. The bracket files are shared on Printables here!

After mounting the switch panel, I connected the circuits for my subwoofer and for the Jurassic Park rear fog lights. The wireless remote lets you set each switch function to one of four options

• Toggle on/off like a light switch

• Momentary switch, which turns on only as long as you hold the button down, like a horn button

• Act as a blinking circuit (like hazard flashers)

• Act as a strobing circuit (like emergency lights)

As I’m toggling circuits on/off, I just used the default toggle function, but I did play around with the strobe circuit for the rear fog lights:

Here’s the how the wireless remote works:
