I have a 1996 Honda Civic DX and I am planning on installing a 97 Chinese Spec B16A4 into it using a 1998 Honda Civic EX Wiring Harness. I am trying to search but honda tech's search engine won't search "How" or "To" because they are less then 3 letters so I can't find a how 2 on how to wire my engine up. I have pluged in most of the wires from the harness, but now I'm having trouble because I have some plugs left over and I know i need 2 extend a couple of them but I'm not sure exactly which ones, and also where some of the other plugs go. If some one could give me a link that would be awsome! Thanks again!

 

More details please? What year Motor is it? What ECU did it come with.. You shouldnt have to extend any wires at all.

Also look here this could help you lots of info.. its the first post on this page you should have read throught that before you made this post

The motor is a 1997 Chinese Spec I am going to be running an OBD1 ecu and I already have the OBD2A to OBD1 jumper harness.

 

You may possibly have to change plugs for your crank position sensor. May be 3 wire to 2 wire or vice versa. Then I'm not sure but you may have to go from 3 wire to 2 wire IACV Plug. https://honda-tech.com/zerothread/1171263

 

you'll also need to extend the o2 wire on the harness.

 

if your using the usdm ex harness plug and play , well i know there wires that need extending but thats cake!

use the obd2-obd1 jumper!

if theres extra plugs dont worry, jdm motors dont have all the sensors that usdm have

plug up all the sensors that are on the engine and if theres extra, for purge control,crank pickup and tec dont worry your runing obd1 anyways!

the ex is already setup for 2 wire iac and vtec so!

 

Chinese Spec, lol

 

you dont think they have hondas in china?
