cancel that, i misread your post.

there is a sub harness on the lower intake manifold that stays with the manifold when you take it off, it could be that something there is s13, and your harness from wiring specialties expects it to be for a s14, but your car is just running the s14 upper

thats weird. that looks like an issue on wiring specialties part. you can make that plug fit if you try hard enough. or resplice the correct one on
your iacv is s13 and those connectors on the specialties harness definately are NOT s14 so idk where they went wrong
