hey guys,

i have a 95 civic with obd2 sohc ZC engine, i boosted the car and i wanna get a p28 ecu and a conversion harness.

problem is, i cant understand the obd2 harness, it looks different.

here some photos of it so please help, i contacted xenocron and he didnt have any solution for it.

 

anyone?!

 

i swapped from obd2 to obd1.

but i don't understand your question at all.

just a guess, you need to unplug the ob2ecu, then plug in the conversion harness, then plug in the obd1 ecu.

 

yes that's what i wanted in the first place, but, this looks different than OBD2a or OBD2b harnesses, i need a pin outs for this harness please

 

post a picture of the plugs unplugged

 

here you go guys

I dont understand your question but it looks like you need an obd1 ecu, then get an obd2-obd1 conversion harness and plug it all in.

 

This is a very rare ECU. I couldn't find any info on it anywhere past that it could be a JDM ECU for a D15B. Not even sure about that.

 

I'm beyond confused, hell i'm way past puzzled. It looks like some sort of OBD2 harness judging from that green connector, but the 2 ECU plugs look like OBD1 plugs, but to further complicate things there are only 2 plugs instead of the normal 3. the 9 after the PC2 generally designates an ECU as being an automatic JDM unit, but i'm absolutely baffled about this.

 

I've seen this before.
It's a bit rare, but last time I saw this was on a Euro EG civic and see that you're from Jordan makes me think Jordan gets Euro model civics.

I don't have a solution either, unless you can snap some photos of the ecu board (with ecu cover removed). If that ecu uses a 28-pin eprom chip, there may be hope to reprogram your ecu.

As for converting to OBD1 normal 3-plug style, I say hit up Rywire. Ryan may have messed around with these kind of ecu's before and has possibly made a jumper harness converter.

PS: interesting to see that green plug too. Its like an EK style harness on an OBD1 car.

 

I'll check up with rayan and see what happens, i hope there is a way to chip and call it a day

 

hey i got a obd2 to obd1 conversion harness & the ecu.. call me if ur interested 416 270 0143

 

thats not what i want, i could do that long time ago, the HARNESS IS WEIRD, not like any OBD2 harness
