My battery harness has seen better days and I'd like to replace it. The wires look a bit sketchy too, any suggestions - thanks

I just bought this - https://www.jcroffroad.com/product/XJBT-PC.html

And i too bought the battery cables from XJwonder. haven't installed yet but they look great!

 

For the terminals:

You can see in the second picture that someone has already once taken off the positive cable and replaced the terminal. It's really easy to do. Just get some marine battery terminals from Autozone, along with some copper cable lugs. Use wire cutters and cut the cables as close to your current terminals as you can get, strip some of the wire off and put it into the back end of the lug. Crimp down, slide lug over marine post. Took me about 30 minutes start to finish.

Here's the terminals that I used:




And the lugs:

 

Thanks guys - just what I need!!!

 

Here's a better option. Military terminals from Amazon, and new custom cables from BestBoatWire.com.

 

What's wrong with xj wonders cables?

 

Nothing that I know of. If you want it done for you, that's a good option. If you want to DIY, it's easy.

 

Ah I see. I guess I didn't browse the site enough. The ones I saw were already made as well. but if they have kits to do yourself that's pretty cool.
