H3 battery cable gauge size?

[rascole]

Does anyone know what sizes all the battery cable gauge sizes are. Trying to finish my dual battery set up this weekend. Going to buy some new connections but these seem kind of small, maybe the large wires are 4 gauge and the small wire is a 8 gauge.

I searched and searched when I did my terminals. I didn't find a definite answer. I used terminals with 4 and 8 gauge lugs. They've been working awesome. Maybe a tad on the big side. The stripped wire doesn't fill the hole as much as I thought it would but once I tightened down the set screw, it's really solid. Im wondering if they're not 6awg instead of 4awg.

Well looks like the larger Neg and Pos are 2 ga and the smaller Pos is 4 ga and 8 ga. on the Neg to body ground.
