hi, im doin a obd1 jdm b16 swap into a 97 civic lx. i was wondering wich harness i should use and if it will be just plug and play? thanks

 

You need to use the stock '97 LX harness. The OBD1 harnesses and the OBD2 Integra harnesses are a 2 piece design, where the 2 harnesses connect at the passenger side shock tower. The OBD2 Civic harness on the other hand, is a 1 piece design, where it connects to the ECU on one side and connects directly to the ECU on the other side. Here's info on the swap, a link to it is in the FAQ page at the top of the '92-'00 Civic subforum:

I copied this directly from another thread I posted it in a few days ago.

Ok, i'm going to try to make this as simple as possible.
- '96 - '98 EX Manual harness.

- Injectors, you have 2 options:
-Option 1 - Cut the injector clips/plugs off and solder on OBD1 versions
-Option 2 - Get a set of used OBD2 B18 injectors. (I perfer this personally)

- Distributor You have 3 options:
-Option 1 - OBD2A B-series GS-R/B16/ITR distributor.
-Option 2 - OBD1 GS-R distributor case, shaft and bearing assembly, coil and igniter with OBD2A CYP/CKP/TDC sensors from any civic/integra OBD2A distributor.
-Option 3 OBD2A to OBD1 distributor adapter harness.

- Alternator 3, possibly 4 options:
-Option 1 - Use an OBD2 B-series alternator
-Option 2 - Swap an OBD2 voltage regulator into the OBD1 B-series distributor (the voltage regulator can be taken from an OBD2 D-series alternator.
-Option 3 Cut and splice an OBD1 Plug onto your engine harness. (I really don't like this method)
-Possible 4th option, OBD2 to OBD1 alternator conversion harness (I'm just not positive they exist)

- ECU Options:
-JDM OBD2A P30 ECU (USDM ECUs will look for sensors that will be missing
-Jumper harness + OBD1 P30 ECU (USDM or JDM)
-Jumper harness + OBD1 Chipped P28
