Well, I soldered up the connectors and put on the new part. Bob, I agree that would have been a suitable solution, but unfortunately the new white connector simply doesn't fit the old black one (that's why it pushed that terminal out). When it pushed out it wore through some wire insulation too so it was getting compromised. I learned a bit on those connectors on
this page; for example the white ones are made by sumitomo and the black ones are yakazi (once again, incompatible w/ eachother).
Anyway, fired it up and I had 13.5v at idle. I call that a win, full test with a ride around the block perhaps tomorrow.
