trouble code P0132 help

[GO_N_H.A.M]

car has the code for high voltage bank 1 sensor 1. my 09 GT500 with roughly 33k has just had a complete wiring harness over haul. dealership thought it could be the solution to some "drivability" issues.

well new harness, same code.

my question is and i am still googling away but im trying to figure out which and where the o2 sensor is, im going to try in replace today so i can solve this issue im having. can some one help and point in me in the right direction?

thanks

well i just replaced both upstream sensors with 2 new bosch ones. code is gone im getting P2196/P2198.

banks are getting .98-.99 on all four so im hoping a retune could just solve the running rich issue....

i guess ill have to wait till monday
