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.

What about something similar - I swapped the engine/tranny and wiring harness - can I use the old 1.6L 4A-FE ECM/ECU, since it plugs right in?
What about the wires that are not on the 12 pin connector from the car that are used on the 22 pin on the 7A-FE ECM/ECU? What about the engines crankcase position sensor - just ignore it? Someone has told me that the 1.6L 4A-FE engine uses a hydraulic shift transmission, while the 1.8L 7A-FE engine uses a computer controlled electronic shift transmission - is this true? What does that mean as far as the swap? Don't both use the ECM/ECU to electrically control shifting?? This post has been edited by Bikeman982: Aug 3, 2006 - 7:53 PM |

Use your old 4AFE engine harness and ecu... and primary sensors that have different plugs. Avoid using the 7AFE harness and ecu. QUOTE What about the wires that are not on the 12 pin connector from the car that are used on the 22 pin on the 7A-FE ECM/ECU? Refer to above. Don't change the engine harness... use your exsisting 4AFE harness. QUOTE What about the engines crankcase position sensor - just ignore it?

What does that mean as far as the swap? Don't both use the ECM/ECU to electrically control shifting?? Is it automatic? All autos are computer controlled mostly for speed inputs and stuff... manuals are either hydro or cable... but toyota did away with cable trannies in the mid 80's... so this should not be a factor. The 5 speeds are the same. Ignore the crank sensor. -------------------- "It's ok to be naked girl... I'm an artist!"
