There are different sizes of picks. Most are flats with a varied width to fit the lock slot groove in the connector. Some are very small and I use a thin round to reach the terminal lock. I use a barrel pick for the weatherpack terminals.Terminal pick? I've never heard of one. I have a pick set and a few dental picks, one of those should work.
Is there anywhere that shows how this is done maybe with some pictures?
What are your thoughts on using a product like CLR?
