If I look in rockauto it comes up as a TPS connector but that doesn’t seem right as the TPS sensor is a 3 wire but the prongs are in a row and if you look up the actual TPS sensor on rockauto none of them match the configuration shown in this picture.

So I have learned that the 91-92 TBI TPS is different than the earlier models. The car is a 90 but the harness is from a 91, which explains why the TPS doesn’t match the connecter.

I think that is also an earlier Throttle body unit which will not accept the newer style TPS

The adapter harness is also available the "other way", for putting an old-style harness into a new-style TPS.
