Ford had this problem with Freestar minivans, water dripping from above the ECM and wicking into the connection causing a bunch of really bad problems. First is to dry it out, then spray with lots contact cleaner, and dry it out again. Then see if it survived, they usually were fine. Then create a shroud of heavy plastic and mastic to shield it from the water. there are quite a few googler videos on the ford. If it was a flood or pressure washing, you can skip the shroud part.

Now I have water that seems to have passed through the thermostat and into the wiring harness and DME. Of course that is not good and it has been recommended that we replace the DME. While I have no doubt that the DME is most likely bad / fried from the water, I'm not quite understanding how replacing the DME is going to keep the same water seepage thing from happening again. Anyone have any thoughts that they would like to share because I am at a loss.
Thanks,
John.

You definitely need to address the water ingress into the ECU / DME before replacing it.
Only time I have heard of water damage to the ECU is when someone pressure washed the engine bay a little too aggressively....
