Cable choice for engine bay (lights)

I was hoping that someone could suggest the best cable to run and also advise on how best to protect cable running through the engine bay?

-I'm adding cube lights to my JLU and running the cable to my factory Aux wires near the battery.

Note that while I can do basic electrical work like changing outlets at home etc I'm not an expert and bring in an electrician for serious work, but lights on my JLU I can do, I just need to make sure I'm running the proper parts.

Should I be running cross-linked cable for the lights? SXL?
What kind of heat resistant sleeve to use for cable running in the engine bay?

With thanks for your help.

Never worried about any special wire for use in the engine bay.
Temperatures do not get high enough in there for anything special.
Go down to your local auto store and buy what hey have. Pick up some wiring loom to keep it neat.

Cross-linked cable? We're just talking about wiring for lights, nothing fancy or expensive is needed. 14 gauge wiring would be fine for those new LED lights, I like to run most of my Jeep wiring inside split plastic loom to protect it. That's the same stuff much of the Jeep wiring is inside of that the factory used. You can find it in the electrical department of most well equipped hardware stores but you'll find a better size selection at an electronics supply store like Fry's.

Thanks @Jerry Bransford , very good to know.
I had pretty much figured these things out after spending some time looking up info online and putting two and two together and now have most of the parts I need.
Just wanted to make sure I wasn't missing anything obvious due to inexperience.

I have discovered I need to practice crimping

- and I'm still trying to figure how to lift the cowl under the wiper on a JL so I can secure the cable away from moving parts. I'll get there!

One thing that can help give a more solid crimp is to 1) make sure you're using the proper size splice/connection for the wire gauge being used and 2) if it allows it, strip a little extra insulation off & fold the bare wire back over itself so it fits inside the connector more snugly. Then crimp it firmly. Make sure the insulation fits all the way inside the connector's insulated sleeve larger diameter part made slightly larger for that purpose.

Thanks for that tip. Been doing some practice and I'll apply your fold the next time.
Will also solder any wire I'm able to.

In the past I've never really worried about wire type; I've always just used whatever gauge primary wire was needed for the amperage being pulled. I've always had good luck with that.

But lately, I've been a little more particular and I've been using GXL. GXL is rated for high temp and oil contact. I then cover that with basic split loom.

The wire I order is like this: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

The nice thing about it is the variety of colors so it's easier to identify later on.
