What Gauge Wires Does the Hopkins HM20041 Use?

Question:

Howdy, What size wires are used in this part? Im looking for a SAE Trailer standard color configuration for my cargo trailer and this part seems to meet that need. Do you have other 7-way trailer-side connectors that are SAE standard? Most everything Ive looked at on your site if for RV standard besides this one. Thanks

I went through our 7 Way harnesses, but the # HM20041 will be the only one that follows SAE standards. I spoke to Hopkins as well and the ground (white) and auxiliary power (black) are 10 gauge. The electric brake (blue) is 12 gauge. The left turn (yellow), right turn (green), tail marker (brown), and back up (purple) are 14 gauge.
