any idea how to remove the hard plastic t supports (where other wires joint into the main) on the engine main harness? i dont want to break it and cant figure it out by looking at it

 

The one on the left is broken off, but it looks the same as the one on the right. There are two in the exact same place on the other side of the "T". They come off easy, but you need to lift up on both on one side at the same time, and both on the other.

 

alright i couldnt see those tabs, ill give her a go!
