Running high-power distribution block under the hood

BigMF · Jun 2, 2025

I'm looking to wire up the winch I've purchased. Initially, I was planning on running the positive wire all the way back to positive terminal of the battery in one unconnected line. However, I was thinking that there might be a need to disconnect or replace the line from the winch and didn't want to have a single, dedicated line. With that in mind, I'm considering running the power from the battery to a power distribution block that can support 350 AMPs with a 350 AMP circuit breaker back near the battery. Then I'd run a line from that distribution block to the winch.

Any thoughts on this approach?

Just started this:

Wiring for a front winch

So, I've been reading a lot of threads and watching a lot of videos on how folks have solved the winch wiring issue. Specifically, making a home run from the 12v battery in the back to some type of wiring terminal under the hood. I thought I would share a few things here. In a nutshell, I'm...

Yes. Better that way.
I also added the switch between the distribution block and the winch ( it’s me: super conservative guy
