I have been doing some research and just getting more lost. I dont know what the correct way or even the only way to wire in the OBD1 LS/Vtec in a OBD2a Civic DX. its an 94 B18B block with a 92-95 JDM B16a head, Can I:

-use the 94 LS engine harness and wire it in the 97 civic( not sure if thats possible)

-Leave my DX harness in the car and wire in necessary wires for vtec and run a OBD2-OBD1 conversion harness(I dont know if all OBD injector clips are the same and also with the Distributor connectors, would I have to convert those to OBD1 as well?)

-Is there a better way?

 

get a jumper harness and run hondata or some type of engine mangement (uberdata, crome, etc.etc.) on a obd1 ecu and there you go.

 

So then leave my OBD2 DX engine harness on the car and wire in vtec? What about the distributor connectors, are they the same?

 

use the obd2 harness.. if you dont want to get obd2 injectors cut/splice the obd1 injector clips to that harness.. you need to change the connectors for iacv and something else.. i dont remember.. i did mine in august..
you need a crank sensor.. the one on the oil pump. youll also need a matching connector.. i have a obd2 civic si crank sensor w/ matching connector ill sell real cheap.. youll need to extend a few wires.. its not hard

 

How about the distributor?

 

as far as the dizzy goes, change the plugs if you know how. use the obd 1 dizzy and the plugs off your obd2 dizzy, and match the wires by location on the plug. or you could cut and splice the wires,
