1970 convertible wiring

Hi Guys! First of all, thanks for a great site! OK, so I'm working on my wife's 70 Convertible. The PO had been chasing a short, and randomly cutting wires. Well, I found and repaired the short, and now I'm trying to get things back together again. I'm now working on the convertible top pump motor. The black wire that provides power to the switch, goes back to the fuse block, and is fed through a type 2 breaker, labeled "POWER ACCY BAT". This breaker is fed from the back, by a 10 gauge orange wire, which has been cut. There are no wires of the same color and size hanging loose, so I'm trying to find out where it was originally connected. I have looked through the diagrams I can find here, but I haven't been able to find it yet. Any help would be greatly appreciated.

black wire is POWER ???

usually Black is a ground .... I gotta look into that ....

10 ga orange with black stripe is ALWAYS full time 12v power thats why its 10ga power seat power windows power top
all run an orange blktracer from the fuse box center holes marked bat

my 67 442 has a breaker on the inner fender coming directly off the battery for the power accesories
then thru the firewall

I have 68 converts and 69s ..... I dont think I have ever seen a black and an orange in line together originally in any of my cars ... factory ...

post pictures you guys it really helps
