HEI in Mopar ECU casing

Well, LOL you do have to be smart enough to understand "what the quip" means.

I can well remember back in my Motorola -911 -dispatch -upgrade days, that an electrician working with us looked me right in the eye and said "as long as you're grounded you're OK."

If you are "grounded', it means there is a potential current path from the source, through you, and to the ground. Sounds like a recipe for electrocution.
