the previous owner of my car hard wired in an O2 sensor and i keep getting a CEL

any help would be awesome the guy hard wired an o2 sensor (b2s1) but i think he did it incorrectly

if anyone can take a quick look, i need to know what color wire is connected to what color wire on the O2 for bank 2 sensor 1, that O2 is against the firewall if you follow the wires the connector is between the battery and TB

on the engine harness side, i have
black/red stripe, black ,brown and a light brown/tan

i have an 03 (i do believe different years have different colors)

any help is much appreciated thanks
