Hi Stacy,
Thanks for your perspective. I hadn't though of damage potentially
incurred while unplugging/pluggin in the ECU.
I did remove the ECU from the wall, tied a 2 foot long piece of
flourescent orange survey tape to the connector, left the back seat
up... and I disconnected/re-connected the plug before I gave it to them
to make sure there wasn't any strange way to disconnect it.
Everything went well...
Thanks everyone for the feedback.
Cheers,
Steve W.
