Jeep Cables upgrade

[jodawill]

I stumbled upon jeepcables.com last night and it got me wondering whether my truck might benefit from some new cables. I think my headlights are dimmer than they should be and I've occasionally had issues starting it up. It seems like the starter takes longer than it should. The starter itself looks great, so I wasn't convinced it was actually at fault.

 

For those of you who've upgraded the battery and headlight cables, what benefits did you see? Is it worth doing? How would you convince yourself it's necessary before spending the money, and how did you decide which gauge to buy? I assume 4 gauge is enough for a stock Comanche.

I would go with the heaviest cables you can afford. 
 

Have you added a headlight relay harness yet? That’s the common fix for our headlights.

Headlight relays are an absolute must!

I haven't, but I was planning to buy them along with the battery cables. How much of a difference do you think the battery cables will make? Does the resistance really increase even without visible corrosion?

I don’t think the battery cables will make much difference in the headlights. You will see the difference in starting the truck.

Yes. Yes it does.
