ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

The rules for the overall forum can be found here:

Read them. You will be expected to follow them.

        It seems that English is not your first language, so bear with me. Are you looking for this information out of curiosity or because it will help with the swap? If you think you need all of the pin location descriptions, then the site linked is all you need. Everything is there. If you want, you can even buy suharnesses already made up and just tie them into your factory engine harness and install the pins into the ECU connector and it's done. Do some reading around here first. Everything has been done before with the H22A swap in these cars.

          Youre welcome, for the H swap all you need to do is add 4 wires(3 if you have F22A6) to the ECU plug.(One fat pin and three smaller pins) And of course use the H's ecu.
          Everything is pretty much in that thread I posted the link to, if you have any other questions use google and type "cb7tuner question/part/etc" and youll get to your answer 95% of the time that way.

          Here is the diagram I was referred to for the pinouts on the ECU and their function

              easiest would be use the F22's harness, and add the 3 or 4 pins, and be done with it

                The easiest way to do it would be to reuse the engine wiring harness from the Accord. That way, you know that it will match up with the connectors for the chassis harness. All you have to do from there is add the additional wires you need for the knock sensor, IABs and VTEC. Since you have a '90 model, you'll need to use a JDM H22A distributor or convert a USDM distributor into an internal coil unit. You may have already done this, though.
