Interesting topic.
Didn't see much in the FSM on removing the various plugs.
Most of the plugs have a tab, that needs to be either pushed or lifted. A few have sliding locks.
Take a good look at the plugs you can get close too and look for the tab or lock.
The sensors on the throttle body are all push-tab type. The tab needs to be lifted away from the plug, while gently pulling the plug apart.
The oxygen sensors are the lift-tab type, the tab needs to be lift up, away from the plug, while pulling it apart
The hood light has a lock that needs to be pulled back, releasing the plug. Other plugs have locks that need to slide sideways.
Before reassembling a plug make sure the connects are clean and they have been given a light coating of dielectric grease.
