PWM cooling fan(s) control using ECM

[Lous69]

I have figured out that there are many Mercedes Benz cars with similar PWM modules that appear to use the same connectors. That makes the search for used connectors a little easier but Mercedes also does not sell new connectors separately.

According to some threads on the Corvette forums there have been connector failures. Not surprising since they have to carry high amperage and are just spade terminal connections.

Since the end of the PWM module is conducive to potting, we are considering just soldering wires directly to the pins for the best conductivity and then potting with an electrical grade potting material.
