Two questions:
1.) Can you read elecrical diagrams?
2.) Do you understand that when you remove the computer, the fuel pump control relay doesn't have a clue when to turn on and off? Leaving the computer in place to control the fuel pump is not quality workmanship.
You can use the wire & relay, however, it requires some knowledge of electrical circuits to NEATLY reconfigure them to work with a carb setup. The stock fuel pump relay uses a ground to complete the circuit & energize the coil. You would have to move several wires around in order to provide a ground for the relay coil and use the ignition switch to provide the power for it.
This assumes that you leave the computer's main engine wiring harness in place. It contains the fuel pump relay,
which mounts under the MAF and near the A/C WOT cutout relay.
The Lt blue/orange wire on the fuel pump relay gets connected to ground. The red wire gets cut &
spliced to a keyed power source. The preferred power source is the red/green wire on the ignition coil.
