What Gauge Wire Is Required On a 7-Way Connector

Question:

I want to make a 4 foot extension on my 7 blade rv connector. I want to know what guage wire i need. I think the power and the ground are different gauges than the other 5. Thanks for the help.

Expert Reply:

On a 7-Way connector the suggested minimum wire gauge for the White (ground) wire, the Red or Black (power) wire, and the Blue (brake power) wire is 12 gauge. The minimum wire gauge for the remaining Green (right turn/brake) wire, the Yellow (left turn/brake) wire, the Brown (tail lights) wire, and the Purple (reverse light) wire is 16 gauge.

I have the Hopkins 7-Way Molded Trailer Wire Connector with Lead, part # H20042. This is a 7-Way blade plug on one end and a 3 foot wire lead. Also, the Hopkins 7-Way Molded Trailer Wire Connector with Lead, part # H20046, which is a 7-Way blade plug with an 8 foot wire lead.

I am including a link to a FAQ page on wiring.
