I have a bank 1 sensor 2 code, is it upstream or downstream on pass side? on 2007 Jeep Wrangler

I went to autoparts store today to buy new sensor and they gave me different colored plug, is 1st sensor on exhaust 1/1 or 1/2, seen a few different diagrams and i'm confused.

SENSOR 2 is always downstream. Behind the converter.

I replaced the sensor, had a friend clear the light, but it came back on afterwards and came up same code and sensor again...
