I noticed quite a few complaints about failures of this connector on the Corvette websites. It's the supply line from the battery to the pwm controller.
In the pics I saw, it looked like the connections weren't solid and had allowed some arcing of the contacts. I checked with Entropy and they told me to expect about 40 amps max for their dual fan arrangement. So, I found a heavy-duty looking connector that's designed for 50 amps (eBay for about $12.00). Not sure if there would have been a problem or not, but decided I was better off making the switch.

If the culprit is the connection from the battery to the fan controller, how will you incorporate those new connectors?

Sorry Andrew, I'm not quite sure what you're asking. I'm replacing the factory connector with this high amp aftermarket connector.
