Slow leak from my rear function for my hydraulic upper link
Coming from around where the house connector plunge into the rear remote
Cleaned the connections
O-ring or seal of some sort?

Since you have quick connect fittings that plug together it can be 3 things
1 connector to tractor threads
2 connector hydraulic upper link threads
3 the connectors themselves.

Leaks can be tough to find. wipe them down and clean with a little brakeclean. I usually wrap a paper towel around them and watch to see where the leak is coming from.
Are they old connectors? You could replace them as a set with new ones. Amazon has plenty.
You can also remove the couplers and clean the threads really well. Reseal and install them tight.

Most, if not all, connectors have an O ring seal in the female one.
Change that as it is the most usual cause of leaks at connectors.

Next a trick to accurately locate leaks is to dust the area with baby or talcum powder, that after having cleaned the area of any grease or oil.
