Jeep gladiator snow plow relay switch and relay box location

[Mattyboy93]

I’m in the process of installing a snowdogg plow on my gladiator. I bought it used and I’m wondering where the relay switch and relay box is mounted since there really isn’t much room. Has anyone else mounted plows and found a good placement for those?

I have a Western Defender plow.
I don't know if yours has a similar setup for lighting controls and relays and such, but can show what I did with mine. You can use what works, skip the rest.
The Western plow has a massive amount of wiring for the lights.
I've had it all on 2 JTs - first time was my 22 Overland, currently on my 2025 Mojave X.
The pictures will be a mix of both Gladiators but other than one wiring run, I did the hardware - the box and relays, the exact same on both of them.

The main box is here, held to the cowl area with a nut over an existing stud, then a brace I may for the front.

Relays attached to an aluminum brace that goes over another stud on the cowl/firewall area -

Another set of relays is here - one end of the brace is attached by the PCM - there's just enough space to add a nut, and the other is in an existing fender bolt but I needed to space the brace up to clear the AC line, thus the plastic spacer ->

This shows the main box going over a stud with a nut holding it at the cowl/firewall area -

So the set up I have is a little more bulky than yours. It’s an older model plow relay box. I like that location. That’s a good location to put it. I would have to see how much harness I have to work with from that location.
The other location I thought is to the left of the battery. There is an angled cavity that I feel I could fit both in. Attached are some photos of the bracket I made to possibly put there. I would mount everything upside down under the bracket if I went this route. I might make a bracket to fit where you put yours and see if I can make it work over there too.

My area next to the battery is full - including with the power cable and fuse for the snow plow, winch solenoid............

interesting. I’ll have to see if I can stretch the harness. Maybe I can separate the two and have the relay switch for the power by the battery and the light relay box over above the brake booster like you have it. I’ll do some playing around Wednesday when I have free time and see what I can come up with.
