Engine Wiring Harness Removal

Hi. I've gotten all of the engine wiring harness removed except I can't figure out how to disconnect it where it goes through the firewall on the driver's side. There's a photo of it attached

And the bolt doesn't come out - you have to loosen the bolt and gradually pull back on the connector until both disengage.

At least that's what mine did...

Out of curiosity, why do you want to remove it?

Re: Engine Wiring Harness Removal

Thanks so much for your help. Once I knew where the bolt was it was simple. I'm installing an LT1 and I've sold this wiring harness with the old engine.
