The Packard weather packs are excellent. I used both the 4 and 3 pin versions. You will need to get both the tower and shroud pieces along with the male and female terminals and the silicon seals. It's a much cheaper way than going to Jegs if you're doing the whole car.
BTW, I didn't buy the crimp tool. I used micro needle nose pliers and also soldered the wire to the terminals.
