You most likely cannot run a hot wire to the orange and black wire. This may power the fuel pump but will not power the auto shutdown relay. You will need to see if the relay is getting power to the light blue and red wire to the relays. This tells you they are getting power. Now the pink wire goes to the computer and should close the circuit when you crank it to both relays. If the pink wire does not close the circuit then you have issues with the ECM or the anti-theft system telling the computer to not turn on the relays. You stated having problems with the anti-theft and should get those problems fixed before condemning the ECM as the cause. You should also have the computer scanned, as you may have a crank or cam sensor problem. I would suggest having a qualified professional, such as one from YourMechanic, diagnose the stalling issue for you.
