You are going to have to mate parts of the Si harness to your stock DX harness. If you need one built then let me know.

its a super easy job. you can do the mpfi swap without chaning the head at all it you want to. some people swear you cant do it without swapping cam/cam gear,but you can. you need the intake manifold, distributer, and all the injectors/fuelrail/throttle body for the si. put that stuff on, do the wiring swap(simple) and plug in the mpfi ecu and your done. for the wiring, you'll need to run 4 wires through the firewall(go through where the ac lines normally do, if you dont have ac, you'll have a rubber plug in the spot). those 4 wires need to be tapped into some stuff, i'm not goin into it right now though, you can search for that sort of thing yourself. its really not difficult.

I'm going to be doing the DPFI->MPFI conversion soon and it's the wiring I'm still sketchy on. I've searched the site, done the links but I'm just iffy on the whole wiring portion. I guess I'll figure it out as I go hahaha

holly **** you attempted the mpfi swap before learning to type......
what computer are you running? have you checked to see WHICH codes it's throwing?
have to tried another resister box? maybe yours is bad. same with injectors.
