I'm trying to remove specific wires from my ECM, I've singled out the wires that I can remove and I've removed them from the ECM terminal. However, in continuing I got to the part where all the wires are collected to go through the passenger fender and up into the engine bay. I don't know what this part is called, but I don't know how to remove wires from that piece, simply because all of the wires are encased in a resin/rubber-like material. Does anyone know the best way of getting the wires out of that piece?

 

The only way is to cut them...

 

The pass through connector needs to be taken apart and soaked in fuel to remove the glue.
there is a wire holder inside the connector that the wire clip into.
efi connector makes a new design for using with aftermarket harness. It’s not a cheap item.

For anyone who's going through the same thing as I was. To remove the wires from that resin/rubber-like material. Take a heat gun to the piece and it will start to melt off, similar to hot glue. Once it was melted enough, I was able to remove all the wires from it.
