Jerry & Cletis,
Could you post a link to one of those oil pressure activated switches?
It sounds like there would be at least two poles on the switch. Are the switches rated at different amperages (or watts)? I can find no information on the 12v amperage draw of a 1983 Motorcraft Model 740 2-Barrel carburetor. All I know is that the instructions say to use a 14 gauge lead from both carburetors to the ignition "on" switch.
I still have to drill-and-tap one of my oil filter fittings (1/2" NPT) for the oil sender adapter fitting (1/8" NPT). So, I could easily use a T-fitting (as Jerry suggested).
If I go with a 6v electrical relay (Hella and Bosch are the only two I can find), if the relay is triggered from the ARM pole on the voltage regulator, would that provide the stall interruption that Jerry describes: " If the engine stalls, the chokes quit heating, so a restart isn't a problem. All the factory electric-heated chokes use some sort of interrupter circuit in case a cold engine stalls."?
Thanks,
Tim
