Exhaust Bank 1 and 2 wire color

[Mrich0908]

Trucks a 98 Yukon with a Vortec l31 I beilve.
I did a tranny rebuild few years ago. Got done this summer doing exhaust work. Putting in LT headers. So nothings where it should be.
I think I may have mixed up the sensors in bank one and two well im all most positive. So if some one who does engine swaps and or knows harness pin outs could tell me the colors for the bank 1 Sensor 1 & 2 and the same for Bank 2 Sensor 1&2 you would be helping me out big time
Thanks.

Any one who comes across this . B1 S1 will have a purple with white wire so will the down stream sensor in B1 S2. The other side will have the same thing but solid purple wire.
