Did some serching and reading..not sure if you are going carbed or efi on your set up but read the warning on jegs site for the ford style starter solenoid:

WARNING! This solenoid DOES NOT use suppression diodes. Use of this solenoid on vehicles with Engine Control Computers will result in permanent damage to the computer/processor.

Im not a wiring guy and am not sure what this means. Being that I am going efi and will have a computer can someone explain this in layman's terms.[/QUOTE]



The layman's definition is: A solenoid is made up of a coil of wire and an armature. The armature is a piece of iron that moves as a result of the magnetic field the coil makes when energized. The movement of the armature operates the switch part of the solenoid. Its just a big relay. The problem comes when the solenoid is de-energized and the movement of the armature past the coil can produce a voltage spike which is seen in all the connected wiring and if the spike is large enough it can affect adjacent wires. The spike that is created will be AC voltage and most automotive electronics have no protection from AC voltage and as result are damaged. The suppression diodes are designed to control this voltage.

Ok, so since I have a solenoid AND fuel injection, should I be ditching the solenoid or will a breaker/fuse take care of the issue? Or depending on how it's wired will I not have an issue?

Does this help? I didn't realize this would be necessary. Glad I started reading this thread.
