KA24DE IACV - different harness plugs?!? Fitment way off...

[90de4u]

My car has been acting up...idling high and such. So I went to the junk yard, pulled off an IACV from what they said was a 92. Supposedly whoever did the engine swap on my car (previous owner) took the engine from a 95. This is a 1990 originally SOHC.So anyways, I pull off my IACV and run into a problem. The connectors on both IACV's are different. On my original one, they are small squares and easily go into the harness connectors. On the NEW one, they are rounded off and I could not get them into the harness because the connectors are too big.

I shaved off the "pegs" on the outside and managed it to plug into the blue harness. The yellow one was a problem though. I had to break off some of the plastic casing on the harness and insert the two wires from the IACV into the yellow plug. I was wondering if anyone else has experienced fitment issues or what??

s13 and s14 iacv connectors are different.

95 engine = s1492 engine = s13

So the S13s would have an updated IACV, with no spring and piston?? And the 95 would have the spring and piston?? I really don't know....

best way to know is to match up part numbers
