Is There a Trailer Side 4-Round to 4-Flat Adapter
Question:
I was willed a really old Wells Cargo trailer which is in great condition. The wiring plug is strange and I need an adapter for it. I can send a photo. It is a small round plug with 4 obvious contacts. Thanks

So I know the wiring harness you're describing, the 4-round, and there isn't an adapter to get it to go to a 4-flat. That's okay though because there is a really simple solution.
What you can do is just cut off your round 4-way and add a standard, trailer side 4-flat, part # W787264.
All you'd need to do is connect the wires with butt connectors # 05731-5.
I've added links below to a couple help articles for you to check out as well on wiring which may be useful.
