I'm going to the JY today to get some O2 sensors ans a MAP sensor for my 01 5.3 swap. My harness is cut and I need the O2 sensor connectors so if I can find some I might as well grab the sensors too I suppose. I don't know whether my engine came with flat or square connectors because that part of the harness was cut. I can find 2 purple/white, 2 pink, 2 tan and 2 black wires for one bank and 2 purple, 2 pink, 2 tan and 2 black wires for the other bank. What vehicles would have the right sensor/connector? I'm guessing there would be a lot of GM vehicles made around that year with the right sensor(s). Is that the case? If I find a GM vehicle with the right wire colors and either flat or square go with that?

Also, what about the MAP sensor? If I find one that looks the same as mine should it be good?
