H-T please help. I am doing a JDM ITR swap into my '99 EK. I know I can't use the JDM ITR wiring harness because it's on the wrong side of the car. My question is, can I use my stock DX wiring harness because it's a '99 Civic harness, and they had '99 Si's.

What wiring harness do I need to put an JDM ITR motor into my '99 EK.

 

What ecu do you plan on using?

I just got done w/ a 96 JDM GSR into 98 Civic Cx using a 96 JDM P72 ECU.

The 96-98 civic harness matched the 96 JDM P72 ecu, all I had to do was add 3 wires (vtec, knock and IAB) the rest I left stock. You'll use the JDM harness for a few clips and that's it on a 96+.

 

My car is a '99 Civic DX Hatchback. We have different version of OBD2. I need to know if I can use my stock Wiring Harness....

 

I'm supposed to have a OBD2-OBD2b harness coming next week for a '00 DX so I can use a 96-98 JDM P73. I can let you know how it comes out....

 

Anyone know if i can use my stock DX wiring harness off of my '99 EK for my JDM ITR Swap?

 

99-00 SI, make it easy on yourself, the JDM itr will not come with a Crank angle sensor, if you want to run one, change out the oil pump to US ITR>

swap king in the flesh,,,, HOLA!

w00t w00t!! Good sh*t, Peagreen!!

 

I don't have time to get an SI Harness. I am doing my swap Tuesday b/c my car isn't running anymore. What do i need to do so I can use my stock engine harness?

 

you can use your stock harness, but you will obviously have to reconfigure a lot of the plug locations. Lots of plugs wont reach, so they will have to be extended. Obviously, you will have to add all the VTEC wires as well, including to the ECU.

Which brings me to your next problem, if you have a JDM ITR ECU, it will NOT plug into your stock harness. You will need to get an OBD2B to OBD2A conversion harness.

If you are going to use the JDM ecu, you do not need the CFK on the Oilpump.

(Which brings me to a correction above... The Crank Angle Sensor is in the distributor. The Crank Fluctuation Sensor or CFK is the one that is on the oilpump.)

With the JDM ECU, you will also not need the VTEC pressure switch, which your motor doesn't have anyway. You wont need the 2nd O2 either. I am not entirely sure if you need the knock sensor or not, but you have those wires on your stock harness anyway.

If you plan on getting a US ITR ECU, then you will need to add the CFK, VTEC Pressure Switch, and change the solonoid to a USDM one.

If you are planning on using a 2000+ ITR ECU, forget about it, as it will have the immobilizer in it. Removing the immobilzer (KatMan $50) will make your ECU diagnotics useless if you dont have an OBD2 scanner as the Check engine light will be on SOLID, ALL THE TIME. This brings you to the pre 2000 ITR ECU's, which throws you back into needing a conversion harness again.

The other option is going straight up OBD1 with a chipped ECU and coversion harness.

Of course, these are all things you should have considered BEFORE you bought your swap.

 

here's my plan, JDM ITR motor with a JDM OBD1 P30 chipped ECU. I already have the OBD2b to OBD1 converter.

what do i need to do to my engine harness to make this work?

pretty much, but the dx should not have a wire for knock. He'll only need to run 2 wires to his ecu harness. the plugs are easy, extend this, change this plug.. the IACV will probably be the most trouble. WHAT EVER YOU DO, DONT CUT THE ORANGE WIRE.

Just kidding, cut and tape the orange wire on the IACV.

Could someone please explain every thing that I need to do in order to use my stock DX '99 Engine harness? I need my car UP AND RUNNING! please!
