my dual port harness falls apart each time i mess with it and it has been botched up quite a bit by the previous owner.

i want to go to a junkyard and pick up a crx si or hf harness and repin it for use in the dx body

anyone have a write up on how to do the mpfi swap this way or just give me input/links to do this project? my shop manuals have no wiring diagrams

 

I know this is going to sounds terrible but if you search in the archive CRX/EF forum you will find all the good info. If you search for it you'll get your answer faster. Also up in the sticky is some GREAT info on this swap too.

i wish i had seen that earlier for some other stuff.

unfortuantly my harness is in very bad condition so i would like to get a newer harness to start with, my temperature plugs are torn up, reverse switch, and many others are already cut and spliced and is generally a mess.

i just need the engine harness pinout diagrams where they go into the car i have the ones at the ecu

 

http://www.fourthgenhatch.com , click on the tech section/how to's/MPFI and scroll down for a complete wire diagram of both DPFI and MPFI harnesses

 

Also you will need to use a DX harness for your car and just splice in the needed plugs for the injectors, distributor and resistor box if you want to go MPFI. So you should be looking for a good condition Dx harness, it will be much less of a headache than trying to get an SI or HF harness to work with your current rig.
