Default 1985 engine harness

Iam trying to pull the engine harness out of a 85 c4. Removed part of it from the center of the firewall but it goes into the drivers side of the firewall. Looks like it plugs in but it doesnt. How do you get the harness out?

That is the C100 connector and there's a bolt through the 'forward lamp harness' that holds both in. This is an '85 C100 from the FSM.

Do you have the FSM for an '85? Did you successfully remove the 'pass through' to the ECM etc on the right?

Here's an interesting thread for you that is also an '85 I believe.
