Man...my head H-U-R-T-S!
I've been sitting here thinking maybe I'm over-thinking things and missing the obvious and then you clear things up by realizing the OEM connector is molded. :crazy:
I'm shelving the project for the week. I still need to buy a replacement soldering set since my friend kept mine when he moved away, so even if I discover that the molded plug comes apart, I wouldn't be able to do anything at this point anyhow.

Looks like you can get the plug.... Item #3
I assume Cooper and Cooper S would be the same?

Hey Erika, stopped by the dealer and picked up some replacement horn plugs. They do come apart, so now I just need to determine the best way to make a jumper. Dealer charged me $3.00 each plug.

Yeppers, it comes completely apart.
It's just the plastic part, the wire and electrical pins need to be reused from what's on the MINI, so be gentle when you take it apart. If you have one of those jewelers flat screwdrivers that will come in handy.

Looking over the instructions, there is actually another way to do it that requires a bit less wiring, but is not either B or C.
It is sort of a hybrid and it what I inadvertantly "saw" when I glanced before. Basically it is most like Fig C.
#30 is power from battery. (using fuse)
#87 is positive to air horn.
#85 is ground (you can make it close to the relay)
#86 is the jumper from the old horn positive. *This tells the relay to close and make the air horn work.
This is how I did it. It requires only a short ground in stead of the long run back to the front and the horns. It also means one less splice or whatever you decide to use.
Just in case it helps.Attached Files:

So I got this fantastic book today, has a wealth of information...
R56 Horn wire size= .75 mm squared or roughly SAE AWG 18 - 19 gauge wire...

Erika, while you are weathering the storm you can think about this....
Posi-Tap..... Posi-Tap- No Crimp Tap
This is a handy way of connecting to the OEM wiring without cutting. One of their retailers is NAPA. This also doesn't require the purchase of a soldering iron..... I'm going to go this route to power the new horn relay for the Hella's.
I'll be down at my shop figuring out where best to mount them. If you get bored with the storm, stop by and you can watch me work....

Sooooooo Much Help Here........
I stopped by NAPA and picked up my Posi-Taps.....
Pretty neat little connectors....
