SOURCE: serpentine belt diagram
There should be a factory diagram at the front of the radiator top plate near the passenger side. That's where it is on mine, and it shows with and without AC. I hope that helps

Hi, I had the same problem with no spark at my 1993 Cutlass. I changed DIS module, Crank Sensor and checked the coils and still no spark. the problem was at the cable between the Crank sensor and the DIS module that was in short circuit. the cable has two pins at crank Sensor and three at DIS Module. (I believe that the extra PIN is the ground because the cable is shielded). The original cable has no isolation. I bought the cable in a yunk yard and the spark appear again. Check it, because this cable is exposed to high temperatures and oil and for this reasson they lost the isolate.
