obd-2 (obd-II) 2JZ-GE into obd-1 (obd-II) body help
I swapped my 96 2JZ sc300 engine into my 93 sc300 car! I got the car to start but it idles at 1500rpm and im not sure if my battery is being charged, i tried to splice the wires and hook pins in proper places also my airbag light on my dash stays on after i remove the key and close the doors! I kept the engine harness on the 96engine. I have searched and searched and cannot find anything all the threads are left unanswered and i would like some help if someone would be so kind to do so! Thanks

I am using the 96 ecu,maf and harness? And the diagrams are you all just talking about the ecu, or the 93 body as well? But i appreciate the help and let you all the results

they are talking about both the ecu and the body, when you swap the 96 harness and ecu and maf, you still have the 93 body harness, so you have to do some repining on the body plug of the 96 engine harness probably alot of stuff is in the wrong spot hence causing your cluster issues.
to repin the body plugs you would need the diagram from both cars, and the diagnostic stuff is completely different standards so the check engine light probably won't work with the 96 engine harness in the 93 and you won't have obd2.
what they were suggesting is instead of repinning and trying to make the 96 harness work with the 93 body harness, is to go back and slap on the 93 engine harness, ecu and maf and there should be no issues then,, and you will also be able to pull codes for you car in the future.
There were 2 paths in the road, and you took the harder one by using the 96 harness and ecu and maf in a 93 car.

Ok so i swapped the engine harness,maf, and ecu (all 93 stuff) and car starts and sound and feels 100% better but still doesnt idle, rpms just drop...no sputter...i havent test drove it just revd the engine....do you think it could be the vaccum lines? But thanks again for the advice you have given me so far! Oh and the engine light came on, there is a plug that i didnt fasten, its on the drivers side close to one by the a/c compressor almost directly horisontal going towards the firewall on the engine block its some kind of sensor, i didnt get to check it was late and dark

I have the EXACT same issue. Problem is, I don't have the obd1 ecu or engine harness. I swapped an obd2 motorset into a bare shell...
so far, I've had to run with a vacuum line unplugged and have had to hard-wire my alternator as well as splice in a connector for it.
OP, when you swapped the old harness and ecu, weren't there some plugs and connectors that were different? And maybe some components that still dont work?

Still have the idle issue, the iavc is different on the 2 motors, the 96 2jz has a "breather tube" that goes to the head, and i found out how to connect the plug....operator error lol
