Under the hood control module

drdfblackm · Wednesday at 11:34 AM

Just looking to see what everyone uses for under the hood wiring management for lights, compressors and whatnot.

There was a guy back in the day when I had my JK that made his own relay and wiring management system....much less than all the big companies but he is long gone. Anyone know of someone that makes these....what does everyone else use? Just looking for cost effective over flashyness.

Thank you.

A number of us use relay boxes, either DIY'd or off the shelf. It was definitely satisfying to have built my own, but having also installed an SPOD in my JKU.....the SPOD was so much cleaner & easier than wiring up an entire relay box with fuses etc.

What is your goal with this? Is it to have a power distribution center, or a switch panel, or what?

Auxbeam is the less expensive option...

I am not necessarily looking for the switch pannel, I have 10000 switches of different types (not litterally, but still a bunch)....I'm just looking for the under the hood relay boxes. I have never thought about building my own....but I have a hard enough time building amp racks and designing them, I figured this is something I should leave to someone else.

I've been thinking about something like that as well, seems I just kept adding and adding now I have relays and inline fuse holders all over the place lol. True Mods looks pretty nice and Amazon has it for only $49 when Real Truck charges $76. Nilight has some interesting lower priced options as well, I've used their fog light harnesses with no issue. The main thing is how many amps do you need? Most of these small auxiliary blocks are 40 amps.

Mounting could be a challenge as well under the hood of a TJ.

This one looks interesting... I've not been able to find a lot of solid-state relay panels.

You got relay boxes like this too but again you've got to find room to mount them.

I used this: https://www.amazon.com/dp/B08KHVHLL5?tag=wranglerorg-20 which is in a waterproof case. How waterproof remains to be seen. I mounted it on the tray under my brake booster, and then wired it to a switch panel in the cab. I also used a distribution block mounted to the fender to make it easier to wire in new accessories. I can't say I recommend this design, however.
