There are several different types of connectors used to supply power from a tow vehicle's electrical system to a trailer's wiring system. Some trailers only need the bare essentials -- running lights, brake lights and turn signals -- while others require a connection for reverse lights, electric brakes and auxiliary power. With connectors ranging from simple to complex, it may be the case that the connection between your vehicle and your trailer is not a perfect match. For example, your truck may be equipped with a 6-way round socket, but your trailer may have a 4-way flat plug. For this very common problem, CURT offers a quick and simple solution in the form of an electrical adapter. An adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and vehicle socket. It easily plugs in your vehicle's electrical socket and usually requires no additional wiring. CURT offers an array of adapters to accommodate most types of plugs and sockets, including 4-way flat, 4-way round, 5-way flat, 6-way round, 7-way RV blades and more. This electrical adapter is designed to adapt a 4-way flat vehicle socket to fit a 7-way RV blade trailer plug. It also includes wiring and electrical components to splice in and route a trailer brake controller connection from the cab of the vehicle. All CURT wiring and electrical products come with a one-year limited warranty to give you the assurance you need to tow with confidence.

nice 3 strand 16 gauge wire
Size: 20FT, Style: 16AWG-3C, Size: 20FT, Style: 16AWG-3C
This review is for a 20 foot sample of 3 stranded 16 gauge wire. 300V capacity. Using a multimeter, I got a resistance reading of 0.2 ohms across each of the three strands (at roughly 68 degrees Farenheit). Specs say 26 strands of 0.254 mm Tinned copper wire are inside each cable. Good flexibility in the covering.

Just what was needed
Size: 20FT, Style: 16AWG-3C
This worked great to extend an electrical line a short distance further than the one that was attached to it. No issues encountered.

Good quality but no more flexible than average cords.
Size: 10FT, Style: 16AWG-3C
The internal wires are good quality with a decent number of strands, but the outer cover is standard pvc, tough but no more flexible than any other cord product. Not suitable for my use on a hand power tool, a rubber cover is better.
