I am trying to make a cis-e test harness for a VW and I was told to use oxygen sensor connectors. What cars came with two wire oxygen sensors? All the ones I've seen in the junkyard are one wire or three wire.

Either late 80's or early to mid 90's Cadillac V8's used 2 wire sensors. Sorry, I don't have the exact model handy. It's in a folder in a file cabinet somewhere.

The connector type you're looking for is very common on old vw's/bmw's/volvos. Anything equipped with Bosch injection will use those two pin connectors in multiple locations.

Yeah I kind find the female end pretty easy but I am having a harder time finding the male end. These connectors look a lot like pictures of Bosch EV1 connectors are they?

The male end you're looking for is on early VW Bosch 3 wire O2 sensors. They've got separate connectors for the signal wire and the power wires. They use them on other things as well. Here's the O2 sensor you're looking for:
