Will a 87 4runner Automatic Trans with the original harness that has the big white plug for the ECT work without the ECT, say with a manual transmission?
What I'm getting at is could you switch the auto for a manual & keep the harness/ecu & unplug the ectl?
is the ECT computer optional or does it talk in two directions?
Are they two different ECU's for manual and automatic?
Thanks in advance
