Mounting a 50” / 40 amp light bar to the roof

[shimmy]

Hi all, not finding anyone who has done this exact set up so curious what folks recommend. I bought a Heretic 50” light bar on Black Friday sale and intended to mount it up on my roof TrailRax roof rack. As I was about to wire up the harness to the dedicated roof plug I realize this is a 40 amp system, and these are 25 amp outlets. I assume the wiring and everything is not suited to handle 40 amps even if I were to replace the fuse (unless I’m mistaken?)

So now I’m trying to figure out how to wire this thing up. I have a harness with everything needed and can expand lengths if i have to. But it will likely have to come in through the roof to a fixed wire setup. Does anyone have examples of doing this? Looks like I will go in through the stock holes where the existing wiring is, underneath the seatbelt trim, and underneath the rear seats to the electrical panel. Are there stock hard mounting points or a bus bar? For the switch… not sure. Would love to reuse a stock switch somehow. The included switch is lame but can use if needed.

Any help appreciated!

Edit: Also for the record willing to just find a light bar in the 25A range for that plug if the juice isn’t worth the squeeze. I prefer low hassle/“stock-ish” setups. Curious what others think.

Correct wiring will not safely handle 40 amps.

The aux fuse box may not be rated to handle that on the circuit as well.

The easiet option is to buy a lightbar rated at 25 amps or below and change the plug to a DTP and just plug it in, like the INEOS lightbar does.
