Coil wiring stock 6 volt

[Vanspeed]

Just got off the phone with Ron over at Sacramento. He told me that he has been making the harnesses like that for 15-20 years. Said he followed a original schematic. He did say that in his opinion it does not matter which way it is hooked up. He said unless it is a race car, there isn't any difference. He said I can hook it up either way. What do you guys think about his response?
