It has a tps plug. You just didn't recognize the round one instead of the flat one.
I ran it with a N* and when local didn't have an adapter, I gave him mine and changed the connector on the harness. Afterall, which is cleaner looking an adapter or a connector that appears original? Same with the alternator, running a newer alternator for the Gen V, cause the 97-99 one was in the way of the IC/bigger cased blower. Even tossed the L32 maps in the box.
I'm interested in this potential fix of reducing the decay rate etc. Because something in my head is having trouble wrapping itself around how false Kr that pulls timing to save a motor from predetonation (or fake detonation) would cause bad piston rod bearings.
