Funny with the same carb set up AMC used the oil pressure switch (79 UP)and Ford used the Field wire on the alternator, so you have your choice. Personally, I have my Jeep wired the Amc way and my Ford wired the Ford way and like the AMC way better, just be sure the way you choose only gets power when the motor is running or it will be like my Dodge motorhome and if you turn the key on for a few minutes then try to start it when cold, it won't start because the choke is open.
