Electrical O2 harness repin

Yes, but about half way down he talks about splicing into the fuel pump relay and pinning it to pin 19 and then putting jumpers from the org/yel and grn/wht wires in the trans harness to pins 6 and 3 respectively to prevent stalling problems.
I was preparing to do this, as I don't want to have to take the seats/carpet out again, but am not sure if it's necessary or incorrect advice.
Again, thanks for any guidance, it's truly appreciated.
