I cut a hole big enough to slide the pcm connectors through.
But there is no grommet big enough (that I can find) to seal it up.

Did you make some kind of 2-piece cover plate to go over the hole?

Fill it with putty?

Some other solution?


(it took a pretty good size hole to get a pcm connector (and the wire bundle on top of the connector) to go through)

Maybe everybody else just pushed all the small stuff through from the inside of the car, instead of pushing the big stuff through from the engine bay side...?

For my Painless harness, the existing hole to the outside of the HVAC panel was larger enough to fish the ECM connectors through. Not sure if the stock set-up is fatter than the Painless.

I then put all the wiring into that plastic convuluted sheathing to encapsulate it. Then I split some fuel line and lined the edge of the firewall. To further reduce chaffing, I placed big zip ties on either side of and against the firewall to keep movement minimized.
