Cable for Toad "Round 7-pin to Flat 4-pin"

Hopefully this is the place place to ask.
I am looking for a "coil type" cable to run from our coach (round 7-pin) to our toad (flat 4-pin). I want sealed connectors on both ends due to weather.
We use a Blue Ox Patriot brake system on toad and therfore need only the flat 4-pin. We have a made-up cable now, but it's not sealed for weather.
Everywhere I have look they are "round 4-pin not a flat 4-pin" and as we need around 5'-0" and the Hopkins round 7-pin to flat 4-pin at 3'-0" one is out.
Please, has anyone seen a sealed cable fitting these requirements? I can't believe I'm the only RV'er that would want this type of cable.

I got a 7 round to a flat 4 pin at Harbor Freight. Around $15, if I remember correctly about 4 months ago. It is a coil type also.

You can order on line or buy in the store. Dean

Get a separate round 7 to flat 4 adapter - available most anywhere these days - and then you just need a coiled 4-pin cable.

Or change the flat 4 to a round 4 or round 5 - there are plenty of 7 pin top round 4 connectors available.

Since you have a working cable, with proper connectors, why not just seal the fittings with liquid spray tape. It waterproofs connections between plugs and cords.

Make your own. I turned a 7 / 7 in to a 7 round to a 4 round. Started with a Roadmaster coil cord, cut off one and and put a 4 round on it.
