Hi,

Thanks for the feedback.

I'm a bit shy about electrical components NOT being isolated in the
presence of un-anticipated voltages, even if if there is no complete
circuit.

This all started when I found out that it's possible to find out how far
away a break in a cable is using electricity (signal waves), even when
there's a break in the cable and no complete circuit!

Here's hoping they unplug the ECU.  I had to leave my van @ the shop,
but I had them write explicitly on the work order to unplug the ECU
prior to any welding.

I did wrap some string around the ECU plug so I'll know if they did or
not!  lol.

Thanks again,
Steve W.
