3SGE > 3SGTE Swap

Good afternoon,

My car is a 1991 Toyota Celica T18.
Recently I swapped my 2.0 GTI engine for a 2.0T (3sgte).

Now I got a problem with the wiring to the ECU. Because the harness of the turbo engine was cut. I do not have the plugs of that one so I kept my old harness. All plugged in well (needed to modify the plugs for the injection a little). The only problem is that the pinout of the 3sgte ecu and the 3sge harness is different.

I want to change the wirering on the plugs but maybe you guys have a better suggestion. Like a pre-made adapter to get the right connections.

This is the product part of the 3sge ECU:
89661-20720

This is the product part of the 3sgte ECU:
89661-2B840

Other suggestions are welcome.

Thanks,
Pascal :notworthy:
