working on 350TBI/700r swap, do I need to get a part to control the torque converter? I have heard conflicting info on this subject, just want to hear what everyone has to say.

Need some more info. pretty sure that the Stock TBI computer would control the lockup.. Is the computer from a 700r4 truck?? Running VSS??

Yeah I will be using the ECM with the motor and tranny all from the same vehicle, 2wd chevy truck. I thought that I would only need the lockup harness if I was using an older motor with the tranny.
