Can you help me identify this differential cooling connector?
I picked up a differential cooler from D3 last week, and while the kit is fairly complete, the wiring is still a rather DIY endeavor. Being a somewhat anal engineer and assuming that these cars are wired from the factory to support the unicorn-like OEM diff cooler, I went looking for the OEM connector to use as a source of power. After some digging, I think I found it under (over?) the muffler. It's a two-wire connector with what looks like appropriate gauge wire, with a cap installed in the plug from the factory.
I wasn't able to find that connector on alldata, so I was hoping someone with a factory service manual (or first-hand experience) could help identify the part number so I can find the mating connector to use for the diff cooler kit. If anyone could help, I'd greatly appreciate it.

Actually, I think that's the connector for the pump itself, which is part of the wiring harness that would be included with the OEM kit. I found the correct connector (attached). The service connector is a ridiculous $60 so I've found the Delphi OEM part and I'll put it together myself. I'll probably also use the same connectors for pump and fan connections (which is probably overkill, but hey why not).
The only question I have now is where the relay location is and whether or not it's installed from the factory. Alldata lists it generically as 'Behind Left Rear strut Tower, but doesn't have anything further' I'm guessing it is already installed, since a relay isn't included with the OEM kit, but I'll probably just wait for the connector parts to arrive and test for voltage.
