i was wondering if i can i use the whole dash and engine wireing for a dpfi to mpfi covert.is the dx dash harness different from the si harness , basicly what im trying to ask is that , will all of it plug up "dash"?

 

I personally think it is a hell of a lot more work to change an entire harness to get a few extra wires hooked up. Just use the needed plugs from the Si harness and run the necessary wires.

 

Sure it would, but your looking at a serious waste of time when you don't need to go through all that trouble. Just use the existing wiring harness, and run the additional wires from that. You will need a few plugs such as injector clips etc. but thats IT. No need for an entire harness, or swap. It will definately save you alot of time. Here's a few links to read up on it.

i know it would be easier to add some wire, but i dont have the dash harness for my car, i just got the body with nothing with the car

 

Ah well in that case, you will NEED to get a harness and yes an Si harness will work for you. That would be your best bet actually since you'll need the plugs anyway.

 

^^^ yea do that ... (i was all ready to help out explaining, but u guys are good)

 

Ah, for some reason I remember a local guy trying to do this in his DX, and the dash harness was apart of the body harness and he had to run wires all the way back to the tail lights.

Lots of work

 

ill do it anyways, nothing else i can do
