wiring diagram ???'s
 

i have a wiwing diagram that i'm trying to decipher for my 67. i need help with the ignition switch. the diagram has an s, c, b, and an a. i think the a is for accessories and the rest i don't know. i need to find what position is the run and which is the start. i'm trying to finish an efi swap into it an this is the last of the wiring i need to do. i really need your help. really. any help is greatly appreciated.

Shelby2, if it's anything like my '66, there's A(accessory), off, I(ignition), and S(start)on the ignition switch.. All the accessories come off the terminal straight out the back of the ignition switch. The I terminal from the switch goes to the I terminal of the srarter relay on the fender apron and feeds the ignition circuit. The S terminal of the switch goes to the S terminal of the starter relay and functions only to engage the starter motor. All of the stuff conncted to the A terminal of the ignition swith is powered when the ignition switch is in th A position or the I position. Of course there is a power lead coming to th ignition switch from the battery the give power to these other terminals. Hope this helps.
