Quick Electrical Question

Does anyone on here have any idea what wires i have to splice into when i switch over to carb. I have to splice into a wiring harness so i can use the existing fuel pump relay and use a lower pressure fuel pump, catch my drift?
I would like a diagram or something, im not exactly an electrical Guru, simpler the better...any help would definatly give me a kick in the ass on what im suppost to do.
 
If your EFI works, why switch to carb? It's a lot cheaper and easier to fix any problems you have than to switch. Carbs are great for the track but not as good as EFI on the street in changing weather and altitude.
 
Im basically, slowely but surely relegating my stang to a weekend only cruiser/track car. Its not my daily driver anymore. Im just more comfortable with a carb. I know how to work on both, i just prefer carb. Its more of a personal preferance. After all im only 18...so, it is cheaper for me at the moment also. Im keeping all my EFI stuff so if i just want to slap it back on i can....
 
Just add your own relay and wiring for the fuel pump, again like with your ignition, all you need from the car is 12v switched on/off by the key to activate the relay.

Leave the EFI harness be so you can switch back later if you want
