Trailer wiring flashers 2000 Cherokee

[rural router]

My right turn signal does not work on my trailer wiring harness. I found 2 flashers behind the cargo wall with all the wiring harnesses. They were hanging down in the bottom of the rear fender. one of them is corroded very bad, and the wires were broke off. Parts stores and dealer were no help with wiring diagram. I just want to wire the new flasher, but don't know which posts to hook to which wires. Here is a pic of the corroded part and a new flasher. I hope I can eliminate the block the old flasher is plugged into, the dealer had never seen it before. I Thought I would just crimp female flat post ends on the wires and connect to the flasher.

I ended up using an aftermarket flat 4 harness that just plugs between one of the connector blocks. If anyone has any ideas about that flasher I asked about first, I'd still like to know, it would be nice to fix the factory trailer wiring.

normally, the signal flasher has three posts, the hazard flasher has two... and of course, normally there are only one each.. do you also have flashers mounted on your fuse panel?

Those are the trailer tow relays, not flashers. Here's the wiring diagram.
