I have a 2000cx hatch and Im putting in a 99gsr swap. what harness do i need ? I tired to plug the gsr ecu into the stock cx harness and only 2 connectors fit.. Will the ex one work ? and also is the wiringharness in 2 pieces ? Or does it come from the ecu straight to the sensors ? also where can I pick up a harness from anyone have one for sale ??? thanks

 

im sorry... you need to do more research... 99 into 2000? uh uh...

 

The '00 Integra shared the same ECU connectors as the 99-00 Civic.

The '98-'99 Integra shared the same ECU connectors as the 96-98 Civic.

I believe starting in '99 is when the Integra gained the immobilizer.

 

96-98 Civic = A, C, D plugs ---> OBD2a
99-00 Civic = A, B, C plugs ---> OBD2b

94-98 Integra = A, C, D plugs ----> OBD2a
99-01 Intagra = A, B, C plugs ---> OBD2b

You can use your 2000 Civic harness.

 

My bad, the 99 integra apparently is obd2a not obd2b. Which means it has the A, C, and D plugs.

Can anyone confirm this. I need another coffee!

If it is the case, you'll need a 96-98 civic harness.

 

I personally own both the 98-00 Teg and 96-00 Civic ETM's....the info above is correct.

However, tyring to put a 96-98 harness into a 99-00 chassis is NOT the way to go.

You need a jumper harness.

And since you're dealing with a 99 GS-R ECU, you need to take care of the immobilizer as well.

I thought this was right. But he tells me that his harness doesn't fit in the the 99 GSR ECU. That's why I'm all confused now.

 

Its partially right.

98-99 Integra = 96-98 Civic
00 Integra = 99-00 Civic

I don't know about the previous year Tegs - I don't own that Helms so I can't say anything about it.

As you can see, he owns a 00 hatch, which means only a 00 Teg ECU would plug directly in, however, he is using a 99 ECU...obviously, not compatible ECU connectors....need an intermediate harness.

 

According to Helms, 94-95 is obd1 not obd2a (I gotta pay more attention when I type, my appologies). 96-98 is obd2a and it's unclear about the 99 teg, but I guess you cleared that up.

 

Just to clear the OBD's up:

1992-95 Integra - OBD1
1996-99 Integra - OBD2A (OBD2)
2000-01 Integra - OBD2B (OBD2.5)

1992-95 Civic - OBD1
1996-98 Civic - OBD2A (OBD2)
1999-00 Civic - OBD2B (OBD2.5)

You MUST use a 99-00 Civic harness only. The Integra harness WILL NOT work and neither will any other years Civic's besides the 99-00. For a GSR swap, the ideal harnesses would be either a 99-00 EX or Si for the most plug and play wiring. You'll need to only extend a few wires and add the IAB wiring. You can also use the stock CX harness and add the needed plugs/wiring as well.
The only way for the 99 GSR to work with your chassis (without a lot of headaches and rewiring) is to purchase an OBD2B to OBD2A ECU adapter harness.
