Good morning and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 18 years and I will do my best to help.

I would not suggest wiring up the upstream and downstream together. What are you trying to accomplish and what issues are you having?

No that was no help I have Bosch o2 oxygen sensors for both upstream n downstream white s go to black goes to grey goes to which colors on the truck?
Expert:  -Brad- replied 1 year ago.

Adam I posted the O2 pinout chart, do you see it?

1/2 downstream

PIN 1 18DG/OR AUTOMATIC SHUT DOWN RELAY OUTPUT

PIN 2 18BK GROUND

PIN 3 20BK/LB SENSOR GROUND

PIN 4 20TN/WT OXYGEN SENSOR 1/2 SIGNAL

1/1 Upstream

1 BKGROUND

2 DG/OR AUTOMATIC SHUT DOWN RELAY OUTPUT

3 BK/OR OXYGEN SENSOR GROUND

4 BK/DG OXYGEN SENSOR 1/1 SIGNAL

If you don't know what goes where the signal wire for the O2 is the Black wire which goes to the Black/Dark Green on the upstream O2. The White wire is the O2 heater which needs 12v so it goes to the Dark Green/Orange, Gray is ground which goes to the Black/Orange..
