What is the Wire Gauge Used in Hopkins Heavy-Duty Trailer Coiled Extension - 4-Pole Round

Question:

Hello - Looking to find out the gauge of the wires used inside this HM47045 pig tail. I am looking for a four-pin round pig tail that uses wires no smaller than 14 gauge. May just need to buy the wire and connectors make it, though. Thanks.

The Hopkins Coiled Extensions with the Nite-Blow such as # HM47045 use 16 gauge wires on the inside. Trailer wiring harnesses usually use 16 to 18 gauge wire for lighting functions and heavier wire for components that draw more amperage. On a 4-Way, you should have left and right turn signals/brake lights, running lights, and a ground so 16 gauge wire will work fine. But if it is for something other than lights then you would likely need to make an extension.

We have jacketed 4-wire, # DW04923-1, which is 14 gauge and sold by the foot. Then you would just need 2 trailer side 4-Way round connectors such as # PK11402 and attach the wires.
