Im doing the MPFI conversion to my DX at the time. I do not know which wires go to which plugs from the DX harness. They are four plugs and the only one I have correct is the TPS plug which I switch the wires like how I suppose to. Which 2 wires from the DX harness go to the IAT plug? What 2 wires go to the EACV plug, lastly how about the other white plug at the side right next to the fuel line. I really appreciate any help Thanks guys

 

help me out please guys

Those are the directions I followed, everything is going well but the thing is that all my plugs on my DX harness are cut except the TPS and I am confused on which wires go to which plugs. I need to know what two wires are the ones for the EACV, IAT, and the plug on top of the manifold.

 

Let me see if I remember. The Intake Air Temp sensor (white thing on the intake runner) has a white plug, then I believe the EACV has a green plug, then I had 1 white plug that was unused.

 

The thing is that all my DX plugs are cut and have not idea where are the plugs I am about to solder going to go. I need to know which color wires go to which plug, for example I know the TPS is green, yellow, and red. But what color wires go to the ITA, EACV and that plug on top of the manifold???? Thanks guys

 

ill check in the morning if no one can get to it quicker

 

Thank you, that will be really helpful

 

Can one of you guys go outside real quick to your MPFI car and check for me real quick? Ill really appreciate it I need to have my car running ASAP because of work

 

I'll go check for you, and get some pics, might as well, I can add that to my How-To.

 

 

That looks terrific!! How about the rectangular plug on top of the manifold, thanks a lot

 

Retangular plug? Hmmm not sure I know what you mean by that. Do you see it here...

 

No its not there, like in the back of the manifold to the left hand side there is square plug that hangs low, right below where its stamped PM-6. FourthGenHatch I really thank you for all the help youve giving me I really owe you. According to my plans Im done with the MPFI swap but its not starting I checked like 5000 times for any wiring errors but its all correct, it seams like Im not getting no fuel any idea? THank you all

 

Are you talking about the TPS? The black thing on the back of the throttle body?

I couldn't tell you where it says PM6 cuz I have a ZC so its not like it would say that on it.

If you can get a pic or find a pic of that thing somewhere I can take a picture of the wires for you. But at the moment I'm not sure what your talking about.

Also are you sure you have spark? As for fuel you did hook up the fuel line again and stuff right? Gas cap is on the car?



Do you see the sensor there?

 

The fuel lines are correct, I took my manifold to a machine shop so I could get a hole in the fuel rail so I could get fuel for the manifold. I think what might be the problem is the distributor wiring. I didnt have the Si distributor plug for the harness, so what I did is cut the Si dist plug and solder the five wires and color matched it to the DX dist plug and the remaining two I installed to the wires I ran from my ECU. Or do I have to switch some wires? did what I did seam right? Thanks for all the help 4genhatch Oh yeah the plug I am talking about is on the right side of the IAT plug, and its not the EACV if I remember the color of the wires are black and blue

bump it up

 

Try switching the 2 white wires on the distributor.

I think he has an Si dist he just didn't have the dist plug.
