I had the same issue and ended up building my own replacement wiring harness, using old connectors. I also went to a junk yard and got a bunch of extras.
You *might* find replacement plastic bits (what the wires plug into) from an electrical store, but I had no luck. Hense, my use of old connectors.
I went to Radio Shack and bought a bunch of inner connectors - the things that the wires actually attach to. They're very common, and are held in the plastic with tiny barbs. Radio Shack sells the tool you use to crimp that in and replace the entire wire.
All you need is a soldering iron and shrink wrap, assuming your old rubber connector covers are shot.
I also bought a label maker, so I could keep track of what wires went to what. If you luck out and find a source for the exact wire-and-stripe match, let me know - I'd send them my business. Otherwise, you can make it work with a spool of wire from Home Depot and your Radio Shack connector kit.
Something I'd recommend is going to a junk yard and getting a used harness as a static display. Take it out of the car and in your garage, use it as a guide for length, etc.
And as much as it hurts my feelings so suggest it, you also might try the dealership or classic center, to see if they have such a harness in stock.
