Dual injector select on crossfire injection.

[Kevin Reynolds]

One of the wires going into the old ECM on my 82 Camaro with crossfire injection is listed as dual injector select.
In looking at the 7747 pinout it doesn't seem to want/need this wire, but what was it for and what function did it serve in the old ECM?  Should I connect it to something on the 7747 or just cut it off and forget it?
