Those look like my tail light plugs. Looks like it hooks up on both sides? I love plug and play, but not at $55. Yikes. I'll end up making my own using a couple pig tails from another early XJ and the late model harness I already have on a shelf. Thanks for the link though.

Are you talking about the connector? Or the converter?
Since we have separate turn and brake lights, and most trailers have combined turn/brake lights, you need a converter to go between them. You can't just connect them.
If you know what you are doing with circuit building, you can roll your own. A few logic gates and power transistors and you are ready to go.
As a "just for fun" exercise, I once worked it out using relays, and it required something like 4 or 5 relays for each side, IIRC. Not practical!

I have the factory trailer harness off of a 99. It has a 'T' connector that hooks it inline with the tail lights. It then has a series of relays, and then the plug for the trailer. The issue I have is the portion of the 'T' that hooks up to the tail lights is the newer plug. I plan to de-pin the connector and slid the pins into the older plug. Will remove the plug end from another 87-90 XJ.
I do not plan to build my own harness. Plan to use a 99 harness on a 90 because I already have the 99 harness, came with the hitch I pulled at PnP.
