Others will have to say or maybe you could go online and see if the Pertronix will work in a Delco. If so and your car is positive ground and has the Pertronix then here is a possible wiring diagram that might partially explain the way your coil is wired. I know the GM 4L60E transmissions in which there have been a couple of Packard installs require some electrical signals to control the shifts but do not know about the 700R4. I thought those only had a cable connected to the carb linkage to control them but I could be in error. Possibly the other wire connected to the coil negative terminal is some kind of tach signal for the transmission????

No idea if it would be useful but here is a link to a site with test procedures for Pertronix positive ground setups.http://www.ttalk.info/Tech/PerPosGndTest.htm
