2025 LC 1958
I want a light bar behind the bumper on my 1958 like this from mandronline. I want to use one of the unused button slots to the left of the steering wheel or the two above the charging ports. Besides the light bar would a wiring harness like this (found the first one on Amazon) be all I need to make it work?
 
It depends on your skill set. I mean anything could be made to work but what is the rating on the switch, size of the switch, rating of the relay and wire gage? IMO running two wires through the firewall to a switch and hooking that to a relay would be much cheaper than that harness. Many "cube" style switches are avail from CH4X4 (pin out for the CH4X4 switch is below).

The link for the wiring harness didn’t work for me, but I wired up a light bar in my 1958 and I’d be happy to walk you through how I did it.

Appreciate the diagram and I had not thought about any of those. I’ll look more into to the option you mentioned.
 
One other question do you plan on adding any other lights or accessories that will require 12v? If so you may want to look into getting a relay/fuse box and set that up. I added a 6 relay/fuse box for more options. I am just waiting for my lights to come in. I am also going to tie all my pod light backlights to one switch/relay that way I can turn them all on at once.

For what I’m planning a front bar light is sufficient enough.
 
Ohhh that looks clean! How did you do that and mind linking the parts you used?

This is a very valid point actually. I promised my wife I wouldn’t go “overboard” with accessories so I’m running just rock lights and bumper light bar. But if you’re looking to do you know, fridge, roof rack bar, bumper bar, ditch lights.. etc, you’re really going to want to get a bit more in depth or shell out for a switch pro or auxbeam or something to simplify everything.

Yep, I plan on adding more lights so that is why I am taking my time and doing my relay/fuse box to be pretty clean.

Thank you for the pictures! This seems something I can handle as long as I take it slow. The fist picture of the red tubing is that the firewall?

No that is the 6awg wire connecting to the passenger side battery positive terminal. That then runs to the 60Amp circuit breaker on the passenger side as well.
