Pins 1-4 power the cable to the d1s bulb, Pins 5-32 two of those need power and ground. Or maybe four?? Four of the pins are bigger. On the other ballast ( which look identical except the more pins and the internals so I can't just try to trace them. Unfortunately those diagrams are not matching up to what I'm looking at. I'm afraid of applying power to the two other pins in fear that it will ruin them.
