On descent on Fytte 4 RNAV arrival; crew was late entering 3rd runway change in FMC resulting in a turn to KURKK instead of JORJO. ATC provided vectors for the approach.
Planning approach to 9L. During descent ORD changed to west flow. We were assigned 27L. Planned approach to 27L. Later in approach we were switched to 28C. I set up approach manually and Captain programmed the FMC. I failed to verify the correct runway was loaded. On the arrival 28C goes to the south of the field on a left downwind. The aircraft continued on the 27L arrival which goes to N of field for a right downwind. ORD arrival gave us vectors that basically followed the correct routing to 28C.
B737 flight crew reported a heading deviation due to the incorrect approach in FMC after several runway changes.
