In Need of a Battery Cut Off Switch Diagram

thanks the 74101 is a 4 post im gettng I agreeQUOTE=67Dart273;1969991920]In my opinion, the easiest is to NOT use that switch. Get yourself a FOUR terminal (DPST) switch, made by Cole-Hearse and others, which has 2 large and 2 small terminals.

Break the battery POS. line with the two big terminals.

The SMALL terminals are to prevent the alternator to continue to power the engine if the switch has to be pulled and the engine is still running ---an NHRA requirement

Run two no14 wires front to rear, and hook them to the switch small terminals.

Up front, if you have a small "trigger" wire for ignition such as MSD, use the no 14 to break the path from the key to the MSD small red wire.

IF you have points, HEI, or Mopar ECU, etc, tap the key "switched ignition" to one no14, and use the other no 14 to key a good quality relay. Use the output of that relay to feed your ignition system.[/QUOTE]
