coreseller,

May I ask the seller ID and part number? Length of wiring harness? Year of your 993? Inquiring minds want to know...

My car is a 1996 NB 993 Coupe, all of your other questions are easily answered by looking at prior responses.

Very helpful, thanks.

If the reference O2 level is pulled through the wire harness than possibly an incorrect A/F ratio at certain times (like idling in traffic or driving in reverse)?

Concerning some of the oxygen sensors being offered for sale as correct fitment for the 993, Bosch part #13723 has a 28.3 inch length overall, far too short for my 1995 993, while #13721 has a 34.3 inch LOA, possible to install, but so tight it can't run through all the retaining clips, so still too short. Further research shows Bosch part #13369, with a 39.4 LOA, to be the correct fitment. Here are some more crossover numbers for Bosch part #13369:
