i'm trying to identify who makes these connectors--the big black connector hanging off the side with the fat white wire coming off the 125 Amp fuse in the DC/DC. The mate also has this fat wire and runs up to the 12V Aux battery. The only markings on the plastic connectors that i can see are "11962" on the fixed end and "11963" on the wire harness side.
Here's a picture looking into the mate which has a crimped socket with locking features. The stationary side has a flat blade like a faston tab, but it is much larger--the blade is 10mm wide and 2 mm thick. The white wire is like 4mm diameter or AWG 6. i broke the white locking tab while trying to remove the crimp terminal, so i need to replace the tab, and get a new crimp lug to make a harness.
