you need to use the DX engine harness and convert it from DPFI to MPFI - you can rob the injector wiring and connectors and distributor connectors from the HF harness when converting the DX harness

No, no they're not. Stop posting if you can't post accurate information.

This has been covered only like a million times on this site. Convert your car to MPFI just like you were going to run an Si or a B engine but plug it into the HF engine and ECU. There is no factory harness you can just plug in and make work. There are people on here you can send your harness to that will build you a harness that will mostly plug in but you'll have to pay up to get it.

In the CRX/EF civic main page, 3rd link down is FAQ (frequently asked questions). Inside that page 13th link down is converting DPI to MPFI. Within that page the second link I clicked on was http://www.angelfire.com/d20/h....html where they explain how to rewire an Si harness to work on a DX. I'm sure if you try clicking on some links you might be able to find an HF harness tutorial.


I know I'm being a dick but seriously, why couldn't you look in the FAQ to answer your own question? I mean that is why it is a sticky up at the top.
