Ok i bought a 99 Theft Recovery Gsr, no motor and Ecu. I also bought wrecked 2001 Gsr with every thing i need to put the 99 gsr together, my question is why are the ECU plugs different?? The 2001 P72 gsr ecu has 3 big plugs next to each other and the 99 has 2 big plugs and a small one. Do i need a 99 gsr ecu? do i have to change anything on the 2001 motor to run? Change main harness? Immobilizer? Thanks.

 

You can drop your 01 swap in using all 01 parts, BESIDES the ECU! You need a 96-99 Gsr ECU

 

Thanks^^^^ Do i have to change the fuel pump?

96-98 ecus are obd2a
99-01 ecus are obd2b

so it should plug in if its a 2001 ecu and a 99 shell, if it doesnt then you dont have a 99 shell or you dont have a 2001 ecu

WRONG!!!

I do swaps all the time! I think you should do some research!

Civic's 96-98 are OBD2a
Civic's 99-00 are OBD2b

Integra's 94-95 OBD1
Integra's 96-99 OBD2a
Integra's 00-01 OBD2b

I can bet my reputation on this INFO

 

Thanks^^. Will the 2001 motor run fine with a 99 ecu?

 

wow normally id fight to the end and never admit that i am wrong, but i did some research and found out what you say is true, and i edited your post with further info

the reason i never realized is that in my state you dont have to get your ecu tested so we all run jumper harness with chipped obd1 ecu

Integra's 94-95 OBD1
Integra's 96-99 OBD2a (96-97 ecus dont have sensor for fuel cap while the 98-99 ecu's do)
Integra's 00-01 OBD2b
