Which one is alternator output connection at starter relay?

I've heard a couple people say they've had good results using heat shrink tubing on a connector with broken clips, to help it stay connected.

Part of the problem with those plastic connectors, is the notch the clips slide over is to tall. It puts more stress on the clips to bend and climb over that notch to fasten. That's why whenever I buy a new plastic pigtail connector, I file down the notch

The new altenators come with that plug. I have had it off 3 times , due to problems that appear to be in the harness. I use a real small ice pick. You basically have to get one side started off and try to hold it and undue the other side. Many parts places sell that plug.
