I recently installed a 2000 typr r engine and trans swap into my 96 gsr. Currently the car is running but on the gsr ecu. i have the 2000 type r ecu (p73-a04) and an ingnition with the immobilizer, but when i went to plug the ecu into my existing harness, only 2 of the 3 clips fit and i dont know if those clips were even wired right.
My question is...what can i do? I can't pass smog and my car isn't running right since the gsr ecu has a code for secondaries. It works, but not like a type r should.
Can i make the 2000 ecu work, and if so how? Does anyone have wiring diagrams of the ecu connectors on a 96 gsr and a 2000 type-r?
Will an older type-r ecu (97-98) work since it wont have the immobilizer? and if so does anyone have one or know where i can get one or the wiring diagrams?

Basically i need to know which Ecu will plug into my current harness. I thought this wouldn't be so hard considering the harness that came on the engine in the swap plugged right into the existing plugs in the engine bay. However i have been talking to a lot of folks and no one can help me.

PLEASE HELP!!!

the problem is you have an OBD2a car and an OBD2b ECU. get a conversion harness or an older ECU.
OBD2a - 96-98
OBD2b - 99+

 

HI
I have an 98 Intgra type r ECU i will swap for your ecu becuse this will sort both of are problems out becuse i have civic with obd2b you have obd2a, mine ecu wont plug in but your ecu would and mine will plug in yours. ECU number P73 (obd2a). Or we both can spend more money on wiring harness converters, not cheap.
Thanks
