Adding on to what others have said.
The Terminal styles are Packard 56. If you find some are larger, they are probably Packard 58 or 59.

The crimpers needed are for "open barrel"
terminals from 18 to at least 12, preferably 10 or 8 gage. The larger gages can come into use with smaller wires when joining two at a terminal. For example at the ballast resistor.
* American Autowire sells a set of proper crimpers
, slightly less expensive than the real thing.
* Astro sells a nice compound action crimper but the jaws are too wide for the male terminals. The little wings at the bottom of the terminals (seen below) are in the way. Terminal removal tool
. Seems silly when a cotter pin or small screw driver will do, but they do save time and minimize damage. I think they are worth it. Best in use is the single prong version. Multi-prongs sometimes interfere with the adjacent terminal cavities.MaterialsWire:
My preference is from a marine supply center. Slightly more copper for any given gage size, tinned surface, and insulation suitable for engine compartments. They also have a ton of colors and can cut what you need. Second preference for engine compartment is wire with insulation for that environment (heat and oil) such as GXL or (IIRC) THWN rated insulation. Otherwise GPT (general purpose primary) is fine.

I found with my jeep, which also used a lot Packard 56 type connectors, not all the terminals were like the original. Not just whether they had a tin plate, but the shoulder stops and lengths varied on some of the replacments. The one on the far left lacks the little wings at the bottom. How important is that?
