I agree.
The 'kit' stuff is usually pretty low quality.
But it's out there. Even auto parts stores (and 'big box' stores) usually have 'extension' kits, 'repair' kits', and/or 'rewire' kits that will have a flat-4 connector (w/ short ground pigtail) on a set length of 3-wire ribbon cable.
I'll be honest. Every trailer I've ever had to repair basic lighting wiring on has used that stuff. Low quality ... but good enough for those trailers.
Be sure to look at everything that's available (within reason). About ten years ago, I needed to convert a tent trailer to 4-flat (5-round permanently spliced to 7-blade, glued into an adapter for a 6-pin rectangular, even though the trailer only needed a 4-flat), while repairing about 6 feet of splices on each side of the trailer. I nearly paid $30+ for a 4-flat 'rewire' kit (12 feet of wire), but noticed at the last minute that a 6-pin to 4-flat "adapter" harness was only $15 and had 15 feet of cable between the ends. Why so much cable, I have no idea. But I got what I needed for half the price, and still have that 6-pin connector in my pile of other adapters, connectors, and pigtails ... 'just in case'.
