I did numerous searches, And yeilded nothing. Ok, There are 3 wires coming from the injector harness, Going to the passenger side... What do they go to, The wires have been cut so I have no clue. The colors are Blue/Yellow stripe, Teal or a blueish gray, And what looks to be pinkish or peach/Black stripe. Any help would be much appreciated...

 

The blueish maybe faded green one and peach/black stripe go to the intake temp sensor... The blue/yellow stripe goes to the dizzy right? What do they connect to is the new question at hand...

 

i believe that what you are seeing is the blue/yellow which is EACV (Si only), green which is the purge cut-off solenoid valve (Si only), and brown/black which is ground - i assume you have Si harness - what engine and car is this in?

 

I'm putting an 89 crx si engine into a 91 civic dx. I assume I'm to take the (TA) sensor plug completly off the si injector harness and use the existing one on my dx engine harness. The only wiring I have for the si is the injector harness.

 

But where does the Blue/yellow stripe one go?

 

can you tell which injector the blue/yellow wire is coming from ?

 

jlicrx, Thanks for the reply. Everyone else, YOU SUCK! haha... I'll figure it out on my own, That shall make me the better man. Mods delete this worthless post...

 

It's not coming from an injector at all, Rather the square 6 pin plug on the drivers side, Parallel to the injector resistor plug. It runs the length of the injector harness and is cut close to the distributor.

 

...

 

Up

 

hmmm...i would have to look at my own mpfi swap when i get my car back...i'll let you know if you haven't already figured it out.....or someone else....

 

Yes, Please... I would appreciate that very much. I have 3 more days to get it in and running or I'll be paying a fine that's half of what I paid for the car

 

ok imma take a guess......
when i pulled the harness from an HF it had that wire.... the only blue/yellow wire that comes from that harness would be the one on the SI dizzy plug......could that be the one you are looking for?

 

I guess, So I dont need it then, I'm just going to make a 2 pin plug at the dizzy for the ca sensor. I guess that on the si It had it going over to the drivers side...

 

 

I've seen that before, It's good and all, But it tells me nothing about the existing si injector harness... Thank you though.

 

would this also work if swapping a newer (92-95) civic motor in? or a D16z6, plus Vtec wires?

 

I think you are talking about that little 2 wire connector on the Si harness that is NOT on the DX harness. It's that little plug that's found between the injector plugs and the injector resistor box plug. That one?

 

I got another question, If your looking at the back of the intake mani, To the left of the eacv. There is a sensor with an ovalish plug, What is it? I've went thru my crx workshop manual, But I can't find anything about it in there... Anyone know? Thanks in advance

 

dont know if this helps but here you go

 

It's whatever this hose goes to. It don't say anything about it in any of the dpfi to mpfi write ups I have seen.

 

i'm pretty sure you're talking about the fast idle solenoid valve ?! you don't plug that into anything and it doesn't throw any codes either. when all is done you will have one plug left hanging from the dx harness. you don't need it unless you live in a really cold place during winter like i do

 

It has been known to get pretty cold around here. Is that one remaining plug for the fast idle joint? If so, I can just change the ovelish plug for the one that fits the dx harness... Thanks again

 

I'll assume that's right...
