Well, you could do it that way, but the way the factory "computer" operates the fuel cut wouldn't be ideal. Assuming you still have the 2 vacuum switches hooked up on the passenger fender, the truck will cut power to the fuel solenoid when slowing down over 25MPH with the brakes on to conserve fuel. Ideally, you'd hook the choke wire to the "Coil housing +" and the fuel cut to the "Fuel cut +"
