I'm not going to say any more about this. Get yourself a big a$$ 50 amp switch and wire it right to the battery like your friend suggested.

It's your rig do you what you want............

Check wire ratings here
Thats the chart I had found, which to me looked like it was rated to 55 which is why I stated what I did, but I then found many more saying 30amps not 55. Thank you for bringing this to my attention, I by no means want a new flame job on my jeep.

I'm thinking I can run two lines [10 guage], In-line fuse [25amp] on each, two switches [rated 25 or greater as two lights = 21.66amp] and two lines up, Inner and Outer lights. then ground.

Sound decent? I found a few 50amp switches that will work fine and are a decent size for the dash, but 25amp switches are by all means a better fit.

[ps, everything is +shipping, as it would cost me more to drive to the store as opposed to shipping... I live a good 90miles from the closest radio shack / autozone / what ever...] | 97 Grand Cherokee Laredo 5.2L V8

10g is good for 50amps at 12vdc and 30amps at 120vac.

for fusing, don't forget that lights draw higher amperage at start up than constant running. fuse for your wire not your light.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
