Yea, i followed the diagram/your advise with the 10ga from my other thread, i'm only using the red factory pump wire to trigger the 40amp relay. I ran 10ga frm pump to relay, 10ga pump ground, and 10ga through the 40amp relay to the alternator charging stud fused with a 30amp fuse. Used 16ga from original factory fuel pump wire(red wire) to the relay, and 16ga for the relay ground.
