ok so I know the basic concept of what to do and everything but I have a few questions I cant seem to answer on any of the how-to sites. Do you suggest using the SI dizzy plug and i also have a whole si harness what other plugs should i use?

 

Just de-pin the plugs and you're set. I used Si dizzy plugs on my LX harness

 

I've already failed at this swap once and then i cut the regular plug off so ill have to cut and solder the wires, But can i use the SI injector plugs and not cut them from the resistor box

 

yes u can and for the other wire thats on each injector cut off at the end of the driver side tower plug i cut my injector resistor wires on the harness not thinking and had to extend them

 

ok that sounds like it makes sense I'm not at home but im going to post colors of my wires up here and make sure i know which ones match up with what. I just really want to double triple and quadriple check everything this time.

 

yea are u using some type of mpfi conversion write up? i hope so but if not heres the one i used

I don't know if this helps but another thing you can do is to use the plug off the d.p. dizzy and solder it to the si dizzy and just get another two wire plug and run them to the ecu. Also if it would look better if you mounted the resistor box on the intake manifold near the alt. so yo don't have to extend the wires to the injectors and run all the injectors to the ecu.

 

Yeah im using one or three or four write ups haha. Thanks tho and i hope that this will be my first write up and i hope it works this time.

 

I was going to do this the last time i tried the MPFI Swap but now that i have the si plus ill probably just use that, hopefully it works this time.

 

aha i had atleast four writes up on my laptop when i was doing it to

 

Yeah thats how i was doing it too but i didnt have the time or a garage to do it into i worked into the night and epic failed i worked 33 or 34 straight hours on it and it really sucked super bad but i didnt do my research at all.

 

I had my ef in the garage for about a week taking my time and doing it right (luckily I have a back-up vehicle); it seems like a lot of people make this project out to be easier than it actually is, I read somewhere that it only took 3 or 4 hours... yeah bs! maybe before you had to fix mistakes and beat yourself up over why it won't run right. I relied on my Chiltons book A LOT more than the misleading and contradicting write ups all over the interweb... I suggest everyone do the same. The wiring diagrams for the EX/SI are side by side with the diagrams for DX/LX/STD making it pretty easy to compare what changes you need to make. I had zero issues, no CEL's, burning smells, etc. when I finished... just a sweet runnin', spunky little half si, half std hatch! haha; Good luck!

 

Honestly..would be alot easier if you just modified the stock Harness, using the SI-Dizzy would make things a bit easier because all you'd have to do is run two wires from the ECU into the Dizzy plug...

Trust me, use the Stock Harness, DPI to MPFI is DUMB easier then it comes off as...I did it..first try, only ran into an injector issue, and I rectified that in a day...car runs like a BEAST now...

 

damn i didnt even think about this at all haha. Yes i read somewhere that it only took 2-3 hours. HAHA It took me 2-3 hours to depin one pin on the ecu. TERRIBLE I KNOW haha

 

yeah i believe that is the plan. Hopefully i can do it in one day when i get home from college im going to pick up solder and a tip for the gun and heat shrink. but i should have everything else.

 

Just don't be afraid to double check things, if you THINK you need to relook something, DO IT, but it's really dumb easy, I did my MPFI conversion in roughly 45 minutes, but in my defense I have extensive experience in wiring as I do alarms, and all types of other ****..still..for even a novice, it's about an hour and half, 2 hour job...good luck man, feel free to PM me if u have any questions on it...


Hell if ur in Jersey i'll even do it for u for 100 bucks, lol.

 

haha i feel you but im in KY i think i can get it but im going to post a write up on here going into more depth than other sites with those fake diagrams.

 

yea its not that hard im 16 and did it, i just had trouble with hooking all the hoses up to the manifold

 

thats one of the really good things is all hoses and everthing are still hooked up so i dont have to figure out where everything goes. My thing was the dizzy wiring was messed up last time

 

Ok I just pulled the whole engine harness off the d16a6 that jumped time that i bought for 100 and now im going to unwrap it and see what i can do with it for the MPFI swap. Pictures to come
