Good morning.
Do you not have power to the injectors? What is the issue that is causing you to do this procedure?

Okay, to power the injectors you need a twelve volt feed from the fuse box to the injectors. it should only be hot with the key on.
do not tap into anything. run it right from the fuse box.

Could I toe into the old ton wires an that give me enough fuel pressure?

for a tuned port you need more than 9 lbs of pressure. you need upwards of 40-50 lbs. you can use the existing wiring from the truck for the fuel pump. that already had a relay for the fuel pump.
