Question about 1989 Jeep Wrangler
I recently rebuilt a 1987 Jeep Wrangler. I need a drawing ..preferably in color of the hoses which go to small solenoid switches on top of the rocker cover..(upstream ..downstream is what the catolog says but I cant dtermine where they go. The hoses go to various places on the engine like the carburator ..exhaust , egr valve etc .. there are some places I have not connected to because I am not sure where they go..
Do you a drawing like this ? Thanks

SOURCE: How many upstream and downstream
Depending on the engine, there will usually be four o2 sensors. They are easy to identify when you get under the car. Follow the exhaust tube from the exhaust manifold down the pipes. You will see a sensor with leads on it screwed into the pipe.

SOURCE: replace oxygen sensors
these engines have 1 upstream o2 sensor and 1 downstream o2 sensor..the 1 in the rear exhaust manifold is the upstream and the 1 after the converter is the downstream..make sure you replaced the right one

SOURCE: oxygen sensor confusion
1/1 is upstream sensor on the number 1 cylinder side, 1/2 is the downstream of the number 1 cylinder side, 2/1 is the upstream of the number 2 cylinder side, 2/2 is the downstream of the number 2 cylinder side. Hope this helps.
