Typically ign switches are labeled BAT, ACC, IGN and if you have a key type starter a terminal labeled START. In a switch with two on positions the IGN terminal is usually only active when a key us turned to the right whereas ACC is active with key right or left. With the Packard switch before late 50 there was no left position so both ign and accessories turned on at the same time via separate terminals. In Packards case the accessory terminal was frequently labeled GA and the ign terminal went thru the armored cable before 48 and was labeled COIL after that.

I expect your loom wire labeled ACC is for one of the late ign switches and is used to provide power to things --radio, etc -- without having the coil energized --typically when the key is to the left. With only the one position on yours it would probably need to go on the GA terminal to provide power to a section of the fuse box feeding those type accessories.
