Swapping 97 5sfe from Camry to 91 Celica gt. I got the motor a transmission in the Celica I've watched how I can just get the motor running but I would like everything to work. I'm concerned with what to do about the stock Celica ecu cause the old celica engine harness unplugged straight from the ecu and the Camry harness runs through both sides of the dash and to the engine bay don't know if anyone's do this or I'm just not seeing it . Hoping I don't need literally everything out of the Camry dash and some how fit it in the Celica just to get everything working.

 

I think it would work with some little modifications
