Bob I also found the under the hood wires, they are taped up on the right side just in front of battery. There are 2 40 amp and 2 15 amp ones, I didn't take note of colors.
That’s great to hear Bill!!! You would think they would put all this info in the manual or maybe I’m missing something? I didn’t get a manual, only have looked at the online one and didn’t see the color code.

Thanks for this info guys. I am looking to install a Rigid 20 inch light bar that is listed at 15.29 amps. I am assuming it will be safe to wire to one of the 15 amp wires even though it will be maxed out. Do you agree?

I'm sure it would be fine but unless you are using both of the 40 amp wires for something else I would use one of them.
That makes sense and I would rather use aux 1 and 2 anyways. I think I will only use 2 of the switches when it's all said and done. Thanks for the response.

No you won't be fine. If the light bar takes 15.29 amps then aux 3 and aux 4 isn't going to handle it at only 15 amps.

I'm still trying to figure why they don't include a grounding wire in with the bundle. I did find a lone wire under the dash that could be for grounding.
Probably to stop people from using all auxiliary switches with just one ground wire. That ground would have to be fairly large.

Yeah makes no sense! I grounded to here:
Just wondering - can you just pop this little panel off by itself? Any screws/bolts to be undone before hand?

This is not a good place for a ground. With so much aluminum used in JL, you should use factory ground points only, to avoid galvanic corrosion at unexpected places.

Appreciate it. Where is There a dedicated ground point in the cab?

There are three factory ground points behind the passenger kick panel near the door hinge.
