In mine, it was red (tip, or front), black (ring or back). I connected red (tip) to the IR, and black (ring) to ground connections of an Xantech input of a connecting block. This worked perfectly.
As did for me - exactly the info I was searching for! I'm using the Harmony Elite...
I also discovered something for the first time in my decade+ of using the Xantech connecting blocks - the 4-screw plug-in terminal is exactly that...plug-in! Since my 791-44 was already installed in my rack...on the backside...underneath a lower shelf, I thought I'd have to completely remove it from the rack so that I could get the two tiny wires stabbed into the appropriate screw openings. But when I was test-fitting on a spare 789-44 I noticed that the terminal pops right out. So I was able to pop out the one from the 791-44, easily connect the wires, then pop the terminal right back in. This wire connects to the IR#1 output on the Hub, and it controls the system perfectly.
I hope this helps someone else in the future, even though I've revived this thread from the dead...
