I want to know....if there is a difference between the two obd2 of these two vehicles ek9 and ek 4...with different years? I believe that they have different on-board plugs. But I want to know if I will be needing a wire harness.....if a power FC that is for an ek9 (1998) will be installed into my 1999 b16 obd2? or it will plug in without any harness to buy?
thanks!

 

96-98 & 99-00 are different plugs

I think the wiring harness is different between the two. Don't quote me but I think its the one under the dash.

 

yeah...the ecu plugs are different. I tried to plug a 96-98 ecu into a 99 harness, didn't work so well.

 

Won't you be out of Reg's for not having an engine of the same model year? Just asking not trying to be a dick it's for my personal knowledge.

Thanks.

 

The ECU plugs between a 98 and 99 EK are different, everything else is more or less the same.

The problem is that on EK civics the engine harness is ONE peice all the way to the ECU. So short of repinning ALL of the ecu wires into different plugs, a new harness is needed.

You are within CA smog laws if the motor you are swapping in is of the same year or newer then the car. But VAFC's or OBD conversions will definetly not pass the ref. And some refs will make you show some kind of proof that the ECU you are running belongs to your car.

 

Damn, you got to be kidding. You guys got it bad over there, they check your ECU!!! Why not just do a tail pipe test and if it passes then who give a shti. I swear, everyone talks about global warming and car pollution, but it is really the SUV's that are fukcin everything up.

 

hey john! come on man...kulit mo ah! i told u it wont fit the 99-00 plugs are diff from the 96-98 damn.. wat a hardhead!!!

 

the 96-98 and 99-00 have different VSS plugs too...learned that the hard way...

 

yea me to the middle plug is totally different had to get the right one and then repin it and a couple other wires had to be moved to other plugs pain in the *** but all good when it was finished

 

Thanks for the info. I just got my 2000 integra book, and I have an ITR harness to use plugs from onto my SI harness. I will have it all worked out before I put it in the car.

 

Ewe! dirty Regs .

 

I dunno about the ecu plugs...i used the Si wire harness and ecu in my 96...but the interior plug is different then the one on the Si wire harness, when you plug tyhem up, your reverse lights, tach, speedo will not work everything else will though...you just gotta rewire the green plug on the interior harness you gonna need a helms manuel for bot the 96-98 and the Si
