questions on push button ignition/
First of all what kind of setup is the REST of the car?
That is --what ignition, do you run an ignition resistor?
Where is the battery, up front, trunk?
IF you have no ballast resistor, you can just wire the push button to either of the "push on" terminals of the starter relay, and the remaining push - on terminal of the start relay goes down to the neutral safety switch
DO NOT run without a neutral safety switch -- for one thing, it's required by NHRA.
If you have a shifter mount neutral safety switch, you can wire that in series with the push button and then off to the starter relay.
Another way to do it, if you prefer to use a rear mount "Ford relay" is to find one --NOT SURE of the application, but I think it was used in AMC stuff. It LOOKS like a Ferd relay, but the two coil connections are brought out to terminals.
AAAAAAAAAAAAAAAAAAAaaaaaaaannnnnnnnnnnnnnnndddd I just got done looking through the Echlin and SMP illustrated guides and CAN NOT freekin' FIND what I'm looking for
Here's the thing. ............There are several ways that some solenoids are wired.
The Ferd solenoid with 4 terminals has two big studs for the contacts, one small stud for the coil, and the coil is grounded to the mount. The 2nd small stud is the coil resistor bypass terminal "I"
Some starter mount solenoids like tractors have ONE end of the coil hooked to one of the big studs. The starter button then hooks to the small stud and to ground, IE the starter switch is in the ground leg
IF YOU can find one of these, you could hook the common stud to the battery, and then run the small stud in series with the push button, to the neutral safety switch, to ground
Somewhere there exists an AMC? IHC? relay that has the coil brought out as mentioned above.
A so called "continuous duty" solenoid will NOT work because it has a weaker coil and does not carry enough contact current for reliable starter operation, due to the weaker contact pressure.
