73-80 front headlight harness

[Roaddogg]

Looking to swap my 86 C10 to a 73-80 front. Im going to look at a mostly complete front tomorrow but has no harness. I was thinking of just building a harness and updating to get some relays in the circuits. Does anyone have a list of all the connectors that are used on the front. I believe everything is Packard 56 except the headlights are Packard 59 if my googling skills are correct. But I'm wondering the easiest way to solve the harness problem since this front clip doesn't come with one.
