Here is where I bought my PWM modules:

You can't open them without damaging them but I was curious to know how the insides of the Corvette version compared to some pics of similar MB units I saw on the net. Here is what the Corvette version looks like inside. They are different than the MB units that look the same on the outside. The MB units do look like they use the same connector as the Corvette units but they will not sell them separately either. I gave up on finding a connector. We are attaching the wires individually with appropriately size female spade connectors.
