Just did a complete oem us spec ITR rebuild on friends b18c1 98 Integra GSR has DNA ITR 2.5 "replica header 2.5" catback, 3" SRI, Port & Polished head. B&M FPR, Blox i/m stock t/b booo runs ok but having CEL issues due to wiring new I/m car just doesnt pull as hard as it should friend failed to lable the iab/iacv/iat plugs he removed off stock I/M. All plugs are round different colors I know 1 is for IAB's, 1 for IAT, 1 for IACV I am aware of this but I have no clue what color goes where all are 2 wire black/red, blue/yellow, green/red, throwing CEL for Intake sensor voltage high or low and it melted 3 IAT sensors so far stock obd2 p72 ecu Im sick of guessing and have no OEM repair manual has anyone done ITR style manifold on 98-01 dc2 gsr chassis cause my 99 LS wires were self explanitory they were already correct length and locations due to LS I/M being similar & having no IAB limited the headaches any help greatly appreciated thanks Idan

 

Someone must have a 98-01 gsr with itr style intake manifold somebody help me out

 

you pretty much just answered your own question. i dont know how much of a help you are to your friend but if just read correctly , you stated you own an integra ls? am i correct? well all of the sensor wiring on your ls would be the same as the gsr. all obd2 and obd1 plug wires are the same colors from the 19848w375089342034298 harness's i have seen in my lifetime. so u can use your car as a reference as what plugs go to which sensors

 

I already tried it the way my harness is same crap cel this car had no cel prior to build

Codes say intake sensor voltage high/low, car lacks power vtec feels really weak

 

Dude its 3 plugs switch them around, you prob have them mixed up

 

Take some clear pics of the plugs showing the color of the wires you are having trouble with.
