EFI to carb wireing Question

Two plugs, one grey, one green, the main wire bundle going into the computer screws out with that green screw. It pulls itself out. There is also a computer relay above all that that needs to be disconnected too. Once that is all disconnected. Go to the engine bay, look where the bundle of wires goes throught he firewall. There should be a rubber grommet there. Pry it out with a screw driver. If its hard to get to, don't fret to take off all those vacuum solenoids in that area, you wont need them. just pull it out carefully.
 
you dont need that stuff, I mean you are allready stepping back in tech, might as well go back before the light bulb also...
It is the easy way out to switch to carb... but it's your car
