I am putting my 94 dx harness non vtec over to my b16a and i noticed that on my dx harness behind the inatake manifold there are 2 little plugs but they all look the same... i know one of them goes on the top of intake manifold by the injectors,

i looked but i didnt find both of the other plugs (it was kind of dark and i couldnt see much)... i only found one on the b16 intake manifold, is there suppose to be another one or what?

 

iac, iat on on top of the intake manifold and the other on the side by the tb
