Well, nothing easy. For my 97,ZJ, 5.2,
Assuming it is the upstream Heated Oxygen sensor, (must be the same for the rear one if you have one), Draw a circle with a small box on the left side at 9-o-clock (box is the lock clip). Going clock wise
1 - dark green/orange - Is the auto shutdown relay output
2 - Black/ tan - Ground
4 - Black/orange- (you are calling a Tan/white)- ? It is the upstream heated oxygen sensor signal.
3- Black/Light Blue -Sensor ground.
On your drawing, lock clip pointed to the Left - Pin 3 is below pin 1, pin 4 is below pin 2.
Before connecting PM me. That Tan and White bothers me. I have someplace a check on this with a multimeter.
