I trying to find out how to make a PT6 ECU that was with an auto tranny into manual tranny. I found a thread for JDM and USDM ECU's How To Covert ECU's from Auto To Manual but the picture looks nothing like my ECU. I also am putting a different exaust mani and pipe in. The O2 sensor is now behind the engine in the pipe instead of in front of the engine in the mani. I don't have a problem re routing the harness only problem is connectors are differnt. Can i take out my old O2 sensor and use it. Also, I am putting an engine with an external coil where an internerl coil was before. Can i just switch out the distributor caps or do i need to switch out the entire distributor or do i re-wire for a external? is one better than the other?
