'89-'93 are all the same for sure. I got a complete mustang harness from a guy on eBay, so that might be a good place to look. Or if you have a junkyard where you pull the parts yourself, it would be relatively easy to get. The dealer might be able to get it, but count on it costing a fortune, if they can even get the harness.

The 4 pin O2 sensor plugs are round and the 8 pin plug is also round. If they were siamese the O2 plugs would have to be 1/2 round.
I will double check, but I don't think that it is a siamese connector.
