1969 Swinger 340

I had a parasitic draw issue with this car that I finally diagnosed today, and I think I've found the issue: installer error (me). One of the times I had the engine out I must have hooked up the ignition run wire to the PCM to battery power by accident, so the PCM was never going to sleep. So now I don't have a .25 amp draw with the key off anymore, lol! It's a pain to unhook the battery every day you drive it with a lift off hood!
