I have swapped engines and transmissions and am running into some questions for someone that has done it. Please let me know if you have.

The stock harness does not have the correct connections for the engine or transmission either.
It also did not have a connector for the engine's crankshaft position sensor.
It would fit the ECM/ECU, but that is supposed to be different for 1.8L 7A-FE.
The distributor part number is also different for the 7A-FE engine.
I have a distributor and that does not seem to be a problem, except maybe that it needs to be set for correct timing.
Do you know the stock number for the ECM/ECU for CA 7A-FE specs?? - should be 89661- something.
It is 89661 -02140 for the 1.6L 4A-FE engine.

The simplest thing for you to do is use the 4AFE harness and just swap over the 7A connectors where you need to. And use your 4AFE distributor. Basically use all the 4A parts you can.

What car is the 7A from, and do you have the whole harness and ECU?
