Default all G's wired for 5th injector?

Trying to sort out a complete cobble job harness for myself, and I discovered that on plug b4, pin 2, it is the power for the RA 5th injector.. All diagrams but the FSM had that pin as not having a wire..
just wanted to see what anyone thought

Plug B4? That does not seem to be in the FSM. It lists plug B43 and B44.

However since the stock ECU is not in any way able to control the 5th injector, it doesn't matter much if you leave it disconnected.

Yes it should be wired up to B4. In the RA wiring, the ECU control wire went to a relay, then to the injector. As Paul mentioned, it was wired but not used on the factory ECUs.
