i have a 2000 civic ex and im putting a 96+ gsr motor in. what modifications do i need to make to my stock wiring harness?

 

none that i can think of your already obd1 wired for vtec and everything else you are gonna need mounts that is bout all i can think of.

 

do a little more searching, has already been discussed. but should be wired for obd 2, not obd 1.

 

its a direct bolt in ... i highley advise upgrading the fuel pump to a 255 walbro and a pressure regulator .... your ecu might need to get mapped just to tune it up a bit.. and i dont think you need to swap your harness but if you do you can get it all on ebay...... YAY BITCH

Don't give wrong advice like this. There's no reason to add a fuel pump or pressure regulator just to get this running. It's crap and don't listen to it. There are several companies who offer wiring diagrams to follow. You will need to use the GSR ECU, and wire in some wires that are not in the stock harness. Does the GSR you plan on using have a harness? If not, you can use the stock one, with several modifications to it.

 

******* A why are you all replying with bullshit info?

(Except for Specail Ed and Whal3 P3nis))

SEARCH THE HYBRID FORUM - ALL OF THIS INFO HAS BEEN COVERED MANY, MANY TIMES AND THE CORRECT ANSWERS ARE THERE, NOT IN THIS TOPIC.

Seriously. I really can't believe the junk that gets posted on here. A fuel pump? Come on, just stick to tinting windows and not making yourself look like a jacka$$.

Integra = 2-piece harness
EK = one piece

You have a EX, the stock harness has most of the sensors on it already (knock, vtec). You will have to add IAB and repin the distributor. Mock the harness on the motor, add the wires, and check the harness.
