im doing a swap on my civic and i need to know which harness i need. im puttin in a OBD2 i repeat an OBD2 jdm b16a in my 97 ek, i repeat my 97 EK. which is also obd2. i'm converting it to an obd1 with a obd1 p30 ecu and a obd2 to obd1 jumper harness. so that means my dizzy alternator injectors now all obd1. ok. with that beind said. can someone please tell me which wiring harness i need??? someone people are tellin my obd1 or some say obd2. SO WHICH ONE IS IT?? HONDA GURUS. please help me out. thanks.

 

use ur stock harness and just rewire some sensors

 

use your stock OBD2 harness, connect it to the engine. then with the conversion harness everything will work fine.
Even if you want to go back to OBD2 for emissions testing.

 

i dont have the stock harness. i just need to kno which i would need to get. i dont have a harness PERIOD. so would i need a obd1 vtec harness or a obd2 vtec harness? or would both or work? i dont kare about emmissions. i cant pass it either way cuzz my motor is jdm. i have to change the pump and sensor and i dont feel like doin that.

 

bump for some help

 

either way will work.
Personally I'd go with the OBD2 harness so your OBD2 distributor, injectors and alternator will hook right up.

 

not to sound like a jerk or anything but..i already wrote that i CHANGED OVER to obd1. including dizzy alternator and everything. i want the wiring harness to be CLEAN . no loos wires hanging out that needs to plugged somewhere. so with that beind said. which wiring harness will fit perfectly and have no loose wires or need no modifcation on my converted to OBD1 swap? and remember it was converted.

 

bump for some more help

 

sorry I guess I forgot or missed the fact that you have the OBD1 stuff all ready.
Since that rules out one of the two options, guess you have the go with the other.

The only harness that will fit perfectly on your setup is one you custom make yourself. Then the neatness is dependent on your time and skills.

If you want something to work with pick up an OBD1 B16 harness (92-95 DelSol VTEC) and an EG SI chassis harness to get to the ECU. (or any model from '92)
There will be some wires to connect with the chassis harness though.
