Electronic Ignition Module Underhood location

Mounting away from the engine seems better, but sure doesn't protect from over-heating. You can find many photos of black goop draining down the inner fender from a Mopar ECU. But, that is more from cheap Chinese products. Some of them even install a fake TO-3 "transistor" sticking up thru the housing but wire them with a little transistor glued to the case. Of course, modern electronics don't need the big box Mopar used in the early 1970's.
