I should have titled "terminal removal" not connector...

Does anyone know if a wire/terminal can be removed from the inside of the car without disassembling the C100 connector on the firewall?
I believe I've found my intermittent power drop to Acc fuse and headlights. You can see black heat marks above the Red wire in G5.

 

Yes, you can use a de-pin tool and pull out the terminal. Disconnect the connections from the firewall side first.

 

You have to remove the TPA (white comb that keeps the terminals from backing out) before trying to depin it. I believe it's possible to get it out from the engine bay side but YMMV.

 

Yes! Good catch.

 

ok so the answer is NO then?., I can't depin from the interior side without pulling the engine side first?

 

No you can but you need to disconnect the two main harnessed on the firewall side and slide up the comb shaped retainer. Then you can depin.

 

That is correct, the catch is on the engine side and the two halves must be separated to get to it.

 

Here's a better view of the terminal:



You can see how you will have to probe from the right side of the image above, (Engine side), and bend the tab down to release the terminal.
