This guage chart seems really heavy. I've been using this one:

If that chart is right, the harness that came with my kc lights is way to skimpy. I'm pretty sure its a 18 ga, which if i was doing it myself would never have used, but figure they arent going to produce a dangerous product.

can you post or send pics........i am about to start my wiring and was looking for a neat way to store the relays...not finding much....any suggestions will help.....I will need about 4 relays for now, but would like room for expansion.

To keep the wire from the battery to the lights shorter and inside the engine compartment.

Edit: oops, you mean the backup lights that only draw 1.25 amps. You don't need a relay for that.

I'm changing this plan thanks to some of the comments, backup light and backup camera/monitor are going to be switch driven with no relay. I should be well under my total amp draw allowed.

Wow. So there is more than one of these "BS" charts floating around out there. I'm sure that there is a scientific formula to back this theory. But this proves that these charts aren't trust worthy.There is one thing that I like about your chart though. If you fallow the 20' column, It falls in perfect alignment with the NEC. And , realistically, how many circuits have you installed ( in your Jeep ) that are longer than 20'?

RE: the OP's original diagram: may be a stupid question, but what is the guage [sic] shown at the very right side, coming from the fuse box, for? Nice work, thx for sharing.

Like it

Plans on getting an aeroforce guage in the future, needs a little power to run it.

Ok, here's my re-worked diagram, this layout makes it a lot easier for me to visualize the load on each wire. I have to confirm every wire length and amp amount I have on here still, but I think its goanna be overkill which is better than problems.
