How can I find the location for the oxygen sensor in my van? The code said the oxygen sensor in bank 1 and I am getting the part from an auto parts store and wanting to install it myself but can't find a picture of where it goes. Don't have a full manual and hoping to not have to buy one. The manual I have doesn't show this. The vehicle is 96 Dodge Ram Wagon Van B2500 V6 5.9 liter.
