I got a wire through the firewall wiring rubber thing but in the process the plastic retainer ring separated and fell to the ground. I recovered both pieces and they are fine. No damage there. But the issue now is how the thing goes in. I have tried a few things but I can’t get the rubber in. So now I’m desperate. If someone can take a picture from the engine bay side I can see how the ring and gasket thing should fit. Any help would be amazing.
