ahh that's your map and TPS sensor not IAC. you should have both of those on your dx harness and they are both the same (should of marked them). If you are missing one you obviously ripped it off.

IAB (butterflies)... big black box under the intake manifold .. you can eliminate it and have the butterflies activate through vaccuum by directly hooking up the little valve up to the manifold

The map sensor on your og motor should have been on the firewall, with a vacuum line leading to the throttle body. I can promise you that if you have an uncut harness, there IS a TPS connector. I believe the MAP has 2 wires and TPS has 3, if that helps you tell them apart.

The connector on the back of the intake manifold is most likely your iacv. The b7 motor should have had one of those too.

The IAB's are the butterflies that control the secondary runners in the gsr intake manifold. If you dont use them, they will always be open.

ok i'm going to assume that you swapped in the gsr into the dx, if that's the case then the map sensor plug is going to be coming out of the firewall...umm hope this helps..

on the black box there are 2 vaccuum lines going into the intake manifold. should i just not hook up the IAB, or is there even a plug on my harness for it?

as stated the one coming out of the firewall is the map sensor..so put that on to the side. now the other ones are going to go to the iacv and the tps...you cant mix those up...as for the butterflies i would wire them up properly but for now just try to get the car started, that way you can at least eliminate the wiring problems that you have...

iacv, tps, iat

back of intake manifold, throttle body, top of intake manifold.

As for the IAB's, you will have to wire them into your harness, or directly to the ecu yourself.

i would use the GSR harness. also, if youre adding plugs be certain to solder them. the top plug is the TPS. if you mix up the two sensors that look alike, the symptom would be the car idling funny (revving up/down at idle) and shutting down (powerloss) under WOT.

yes, US spec would be what you need, since the one youre using is for a RHD car.

i understand, but you must solder the connections of extension points. you will get CEL's from the KS or other sensors if you just tape them up. save yourself the headache.

your pics suck. Get brighter ones, and show the shape of the plug, and the color of the wires.
