Ford tow harnesses and other items

[Studiovette]

After 2 weeks of owning my new Greyhawk I just found my manual with these harnesses. I was able to google the part numbers and see that they are for towing but not sure why there's 2. AB & EB? I have no idea what the little black box is that looks like it plugs in somewhere. Flux capacitor? Lol ?

I also found a short drinking hose in one of the cabinets. Not sure what thats used for.
I was missing the privacy curtain and located it! The only thing still missing is the LG over cab bluray player remote. I'm sure it will turn up somewhere.

The hose is for drawing antifreeze or sanitizing solution in through the City Water connection using the onboard water pump.

The wiring I am less certain about, one may be an electric brake controller hookup harness, the relay may be to enable the charge connection to your 7-way tow plug at your trailer hitch.
