i have a b16a harness and I have a 90 CRX Dx. Now in the engine bay pass. side, i have 2 plugs in the dx. and on the Sir harness, i have 3. Can anyone tell me what the wires in the 3rd plug are for? Your help is greatly needed. Thanks!

 

it has to be either an oil pressure swich, vtec selonoid, knock sensor, or second o2 sensor. what number harness is it on.

 

well the jdm harness is for a right hand driver car and would be a hard switch over to the left side driver and some of the plugs will all click in the some of the wires are in different places and will throw codes on the ECU. The best thing to do is get a USDM 89-91 Si harness ( or hf ) out of either a crx or a civic, then it will plugs up and you will have to just add 5 wires including the wires for the vtec activation to the ecu, do yourself a favor and get the connectors that you can unplug from in the engine bay, this makes it a little easier to work.


91 Si w/b16a and ITR intake manifold, port matched throttle body, lots o' suspension work. And still learning to drive it.......

 

you cannot use the b16 harness and just plug it in. you have to get either an si harness and add the 4 plugs, or add the 4 plugs plus the mpfi plugs onto your dx harness. it's not that hard just takes some researching.

er nevemind, i accidentally skipped over that last post. i have to second getting the plugs that you can take off in the engine bay for the vtec solenoid, etc. just run those wires, put a plug at the firewall, and from the second half of the plug run the wires to your ecu.
