Review: Good trailer 7 plug with wire - It appears to be good. The wires look like pure copper (no filler), the gauge are accurate (minimum of 1 gauge smaller) and the outside insulation is thick and tough. The plug fit in my 26 F150 perfect. I only have a concern, it's in July now, when cold weather, could be stiff. I would buy again.
