I never noticed how much noise comes through this area around the connectors.

There's insulation on the other side of the bulkhead plus the ECM is surrounded by the rear console compartment with plenty of insulation in there. I've never noticed any objectionable sounds. Maybe someone with a better set of ears than mine will chime in later.

The noise will probably go away once you put the storage bin back in place.

Pull the ECM to see if the transmission cable grommets are still in place. Lots of heat and noise can enter if they aren't securely installed.

Careful on the foam, the ecm needs some airflow around it for cooling.

Anything I might say is probably worth what you paid for it, so treat it accordingly!

Wires are sealed by "re-entry encapsulation/potting" compound that removable by hot water I think.

Closest thing available and cheap to that for public is maybe Latex Interior caulk.
should not permanent glue the plastic in case you need to remove it later.

also See my Cave, ECM Heat
Entire case must have plenty of air because ECM/PCMs will die w/o enough air to dump heat.

Thanks for the information. I am not removing them. I just noticed with console off to address a different situation that it was very noisy and you can see daylight when looking out into the engine compartment. So I was looking for ideas to "seal" the area up from engine noises.

In my opinion the noise is good. When you want it quiet have the console on but if you are listening for a problem, you can more easily hear it with it off. Used that to my advantage a few times

There really shouldn't be any openings into the engine bay. Pressure from air flowing up into the engine bay can bring exhaust gases into the passenger compartment. I discovered this when work was done on one of my Fieros and the transmission cable grommets weren't properly reinstalled.

Where exactly do you see light from the engine compartment? Through the wire bundles? If so, you'll definitely want to seal the wire bundles using a latex caulking as mentioned by Ogre.

I used chalk I think it is silicone. Any the plug that was redone for the swap had the "holes".
