Default E38 PCM fuel pump trigger

Hello to all. I’m attempting to diy a LY6/TR6060 wiring harness to crank and my engine and transmission. On the net and LT1Swap, it stated that the E38 pcm fuel pump trigger is #50 pin and leads to the under hood fuse block. When I traced it, I was lead to a connector at the rear or my LY6 engine harness by the rear O2 sensor. Can any one explain this?

Dark green wire in pin50 is right, maybe that plugged into something else then went to the fuel pump relay. Did you double check to make sure you followed the right wire? If so, I would just use the green wire to control the relay and not loose any sleep over it.
