If
you have a 1994-95 TBI engine and transmission that will become part of
a project then check this out. The transmission, 4L60E is an electronic
transmission and requires the ECM to do all of the shifting and down
shifting. Most of us are not into the electronics being part of the
transmission but think about it, with the ECM controlling the shifting
and down shifting, it makes it easier to modify the shift points. Shift
later, shift sooner, hold first gear longer etc. Programming software required.
This harness will get you there
with a pull out engine from a 94-95 GM truck.
We sell this harness for
people wanting to install a 4L60E or 4L80E into a non computerized engine and car
as well. People have used this harness to do the transmission
conversions like putting a 4L60E or 4L80E behind an older engine, yes
even CARBED engine. The harness has the RED and BLUE connectors for the
ECM numbers 16197427 or the 16196395 ECM only. You will NEED the speed buffer module from the donor vehicle for the speed signal that the ECM uses
To do a conversion you will need the following signals to the ECM, coolant temperature, MAP sensor, engine RPM and Throttle Position Sensor. These do require the original type of speed buffer or “DRAC” module to calculate speed by tire size and gear ratio. You can get a module from almost any speedometer shop or from a donor truck or van. Check out Jags that Run for what they have to offer in the way of speed buffer modules, they are adjustable and seem to be a good product.
We have been manufacturing these harnesses since 2005 and are on engine swaps like yours located all over the world. These are a time saver and will make your swap pain free. These use your Red/Blue connector 16197427 ECM or the 16196395 ECM manufactured from 1994 to 1995. They have provision for 4L60E, 4L80E transmission. This harness comes with the following connections:
