Ballast wiring

I started an entire thread about those terminals, which is now a sticky. The two types sometimes can interchange but sometimes not because the terminal won't fully lock into the OEM connector housing. I don't know how much clearer I can make it. Click on the link. For some reason when I post links, they show a large snip of the post instead of a URL. @Joeychgo is aware of this and did not have an answer.

When I'm feeling generous and have the time I can go back to the post and edit the code. I am not feeling generous this week. grump grump
