Electronic ign/ This is what i got

If the box is a 4 pin (you cannot tell by counting) you can use EITHER a 2 or 4 terminal ballast

If the box is a 5 pin you MUST use a 4 terminal ballast.

The previous folks who converted my 67 mounted the box just to the side of the wiper motor. If you have A/C you can't do that. I'd mount the box over on the drivers fender apron, and put the resistor/ regulator back where they came from.

Make ABSOLUTELY sure you scrape the paint clean on both boxes, and use star washers for a good ground. Make SURE you have a sizeable ground from the block to the body. I used a no4 starter cable (eye to eye) about a foot long, on the rear driver's head unused bolt holes on rear of head, over to one of the master cylinder bolts.
