Gotcha.

More than meets the eye!

No. Haven't heard my "1.9" 2 spd. fan kick into high speed but do
understand that the noise level is somewhat noticeable.

I assumed that "simply" comparing wire gauges would suffice. However.
At the very least, research would mean trips to the library perusing
electrical diagrams for various (V6 or larger?) popular makes of
vehicles.

And I ain't *that* bored.     ;)

Neil.
