damn man. i'm been trying to find help and i'm not getting ****. i'm trying to convert my DA's obd0 setup to the OBD1... what harnesses would i need? one guy from a junkyard told me i could just change the injectors plugs and that's it... what do i really really need in order for this conversion **** to happen!? PLZZ!!! my car's throwing up codes... it's already throwing the atmo pressure sensor (code 13)!~

 

You can't just change injector plugs because that's not even the issue. If you changed the plugs to run high impedance injectors then you'd need to rewire out the resistor box which isn't a big deal, it's just totally unnessecary. The main thing you do need to change is the distributor to an OBDI or OBDII one (they're both internally the same, just use whatever connector you need). Besides that you'll need to make or buy a nonOBD-OBDI jumper.

 

Contact Blown90hatch. He makes excellent conversion harnesses and gives excellent tech support. He will also beat any advertised price. https://honda-tech.com/zerothread?id=997093

You need 4 wire o2 sensor, obd 0 to obd 1 conversion harness , obd 1 or obd 2 dizzy, obd 1 ecu.

 

****, I knew I was missing something but I couldn't remember what... Yea eda6 heated oxygen sensor circuit.

 

alright ht. thanks for the help.it's just that when i get it done. i don't wanna get ripp'd off for the people who are gonna do the work to use long terminology to try to get more money out of me.. thanks. but can i avoid takin it to the shop by doing it myself? what's the difficulty scale 1-10 for something like this to do on my own?

 

If you're fairly comfortable with wiring and you understand most of the basics on a Honda you shouldn't have a problem at all. I converted my friend's Rex ~3 years ago to OBDI and at that time no one was even really making jumpers. Just take your time on setting up the harness and you shouldn't have any problems. Again I've posted this a ton of times but here's what my jumpers and reworked nonOBD harnesses look like. I'm extremely **** about this kind of **** tho...

All Done

 

Kataku2k3 gets for that harness. That's excellent work. It looks much better than my rat's nest . Is that a 2/3 bar pigtail and connector I see as well?

I used wire nuts at first to check my work. After I was code free I soldered everything and used heat shrink tubing.

Heat gun+soldering iron+1/4" heat shrink tubing=very clean install

If you get a harness from blown90hatch the difficulty would be 2.

 

Thanks, yea that's a GM MAP connector. Will used this harness for one season with his B16 turbo motor and Hondata. With his new motor we're running Motec so we'll see how clean I can make that harness...

 

that harness looks better than factory

 

daayam... that **** looks hella complicated tho... say if i did have the harnesses.... where do i start?
