I've already tucked the drivers side of my bay, now I want to do the passanger side.

I have a near complete 5 speed D16Y7 harness OBD2 harness and OBD0 ECU plugs. Will that harness be easy to convert to OBD1 and VTEC? I would keep my OBD0 to OBD1 conversion harness and just solder the OBD0 plugs onto the OBD2 harness.

Where could I hide the fuse box? In the glove box?

Some issues...I'm missing some plugs, forgot I cut them lol, and quite a few differences. But I had to expect that being OBD2.




Have to put on a tempature sensor, get rid of the extra o2 wires and the extra mystery plug.



Dizzy has one plug vs. 2 plugs and 1 more wire on my CRX dizzy.



Big, random plugs.



Alternator plug is different and has 1 less wire than my CRX alt plug.



Unknown plug. Maybe TPS?



Have to change the injector plugs.



Have to put on the MAP plug and some more unknown plugs.

 

OBD0 car, OBD2 harness, and you want to convert to OBD1?
????

Get an OBD1 harness jumper
OR
an OBD1 engine harness and OBD1 ECU plugs so your color codes and ALL sensor plugs will be proper.

 

just a random question sorry, but would you be interested in sellin those obd2 injector plugs...doin the wiring yourself i trust you know where to cut them to re-use them. if you're up for it shoot me a message with a price thanks

 

im a little confused on why you even needed these harness? you should retain your original harness and just extend and shorted whires where you need to... and i def confused on the obd2 all together? no need for that anywhere, who converts and ef on obd2???

 

Well I think now I'm going to use the harness thats in my car and just alter it to hide the wires. I was thinking of using the OBD2 harness because all of the wires went into the ECU plugs so there were no plugs mid-way.

JDM DB2: It might cost too much shipping them over the border if you're in the US, like you could probably get them cheaper where you are.

 

that giant plug with the yellow(orange looking) with black stripes are for the injectors. trace the wires and De-Pin them. (best way to sell them)

and unfortunately you cant use the obd2 harness in your rex.you MUST use your OEM harness and extend.Or how i am doing it De-Pin and use the wires NEEDED/USED on your obd1 ECU.

 

be smart and run your wires thru loom and make sure you put rubber grommets wherever your wires pass metal.

just look @ my thread lol. i have 3 different harnesses (4 including my DX)
i just picked up that obd2 harness for the plugs since my motor is obd2 but i'm obd1. get me?

 

I know its hard to use the OBD2 harness, I have to alter a lot of things.

I think the best way to do it would be to plug in all of the sensors into their proper spots, run the wires through the firewall, cut/lengthen to proper length, then wrap them up. Then change the ECU plugs to OBD0 so the completed harness would be OBD0. Then plug it into my OBD0 to OBD1 conversion harness then to my OBD1 ECU.

 

remember you have to take into consideration your cabin harness.
but the only way to find out yourself is bye doing it how you want so

 

how old are you, to know that you know how all that works, I just got a headache looking at photo's

 

rt, I'll have to plan this out well and take a lot of time lol.
I'm 16, I did everything to my car, it was stock before.
