Is there a problem with installing a hondata system with an IAC that has 3 wires comming out of it? I just read this https://honda-tech.com/zerothread?id=599148 and I want some sort of confirmation. I was told by secret services that installed a p28 and a hondata system on my 6gen accord would be no problem.

 

Help, anyone???

 

bump

 

Only done this on OBD2a to OBD1 harness, here are my notes:

On the OBD2a connector put a jumper across terminals A12 and A14 so that they connect to the A9 terminal on the OBD1 side. The third wire is A13 on the OBD2a connector and it goes to A23 on the OBD1 side.

If you have OBD2b car, I can probably advise, but, well, I'm ******* lazy and would rather not lift a finger unless completely neccesary.

 

Is this OBDIIA or OBDIIB ??

 

Goddamn you, OBD2B. How dare you make me work

 

If you read this thread https://honda-tech.com/zerothread?id=599148 I hope the installer just didn't know how to wire this setup.

 

If I'm understanding this correctly, I have no OBD2a/b wiring diagrams in front of me (anyone with a Helms, scan and email pls pls pls?) the two pins you worry with are OBD2b B6 and B23. Switch those two in the harness, and all should work.

I have a few emails off, hope to know for sure tonight.

 

Thanks a lot for your help. I hope you get a write up soon for this. I'm suppose to get everything done within 3 weeks.

 

i play no part in this thread, but thanks j. davis for the info

 

I'm just trying to get my car boosted so here is another bump.

 

Anybody with a diagram of OBDIIB please post!!!!

 

OBD2 Helms ECU wiring diagrams needed, pls. I have neither test vehicle nor information to go on right now.

 

j.davis, this is the ecu pin layout for obd2b (6 gen accord)...will this help?



thanks in advance!

edit: oh damn, i just realized that i'm missing 1 more page! i guess that's the page with last connector which would include IAC?

come on guys.......one more picture and I'll have the hondata figured out.

 

stinker, you might want to try other forums?

 

I'm asking all major 6gen accord forums but they all have that diagram. Most of them all want the vtec wire and don't bother scanning the other page....I'm working on it

 

Okay I give up.....I'm going to honda tomorrow and asking them to photo copy me that page.
