A good source/s for electrical/harness', small/large, terminals, connectors, etc., that I don't need to take out a second mortgage to buy.

Did you ever Check out Charger Specialties ?
I have used them to repair the wiring on my cars they have a good selection of factory type pins connector ends and such. web page

guess it depends on if you plan on going stock or just do a better job on wiring.

some of the places I have ordered from. weatherpac connectors and bulk wiring and such. not stock, just better wiring.
sockets and such were cheaper at the local pepboys.
