Have just recently purchased a 91 fc with t2 conversion motor and tranny, the question I have is what the seller tells me as how he hooked up the motors wiring to ecu. He told m he kept the NA ecu and only had to swap two wires to make the t2 work....anyone ever heard of this or was I getting a line of BS cause he knew nada about anything I was asking him?

 

maybe he kept the N/A harness and only changed 2 wires to run it?
check the ECU to see if it is the N/A or TII.
N350 is a N/A and N370 is a TII.

 

OK ill do that tomorrow soon as I get off work, but would doing that cause any kinds of damage to anything? I've never heard of anyone doing that in my years of working on em?

 

I did mine with an N370 ECU but modded the NA harness for use with T2 motor

 

maybe you misunderstood

 

Maybe he said that he used the NA harness and only had to modify two wires to make it work with the T2.

That could be correct.
