I have the 45amp PP contacts, and found a very easy way to solder them up. I take some side cutters and trim about 1/8" off the 2 "ears" (the pieces that you fold over to crimp the wire in). I do this as you cannot get the contact into the housing if these ears are not bent or cut. Then I lightly tin the connector, tin the wire and solder them together. I use the bench vise to hold the connector by the contact tip, but a pair of vise grips would work too. Super easy, I can put 3 to 4 times the number of PP together compared to deans, and no shrink to worry about.
