The how to section talks about a red collar, but obviously the design has changed. Studied the connector, and it's not obvious. I have searched the site and the web, with no luck. Don't want to break the connector screwing around. How exactly are you supposed to disconnect this?

Squeeze down on the part with the ridges and pull back, if it won't squeeze down you may have to push that blue collar in or out. It's not that fragile

Pull the blue tab to the right. Comes off like a regular connector now.

Yup, move the blue tab to the right, then push down on the striped tab in the center while pulling does the trick.

First rule to follow is do exactly what you did, try to find the answer here. Me? I broke the blue tab....then searched and immediately found the correct way to do it here on the forum.... After doing quite a bit of recent engine work I noticed the theme: colored tabs, blue, red, grey, etc. is the way to communicate that the colored tab needs to be pushed or pulled in some fashion then typically squeeze the tabs. Some of these connectors are incredibly complex to figure out....like a devious one on the steering rack....
