This listing is for GM style Throttle body fuel injection wiring harness for engine swaps, also called TBI.

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:

ECM connectors
Fuel Pump relay, includes relay
obd1  ALDL port
Fuse block
MAP
Round 3 pin TPS (if yours is flat let us know)
Coolant temp
Flat 4 pin IAC ( If yours is square let us know)
Injectors pigtail with rubber grommet for sealing at throttle body
Heated O2
Oil Pressure Switch
Knock
Round 12 wire transmission plug WITH OUT a screw in the center. (if your 4L80E has a screw in the center, then we need to talk)
Speed VSS
ISS if 4L80E

These are sold as 4L60E harnesses and if you are using 4L80E let us know when you purchase so that it is set up for you that way.


4 pin connector for remote coil type distributor 85-96 small cap style
* you will need the 2 wire jumper connectors from your coil to power and to distributor, they can be found donor vehicle
This harness is covered with GM corrugated slit loom, not the cheap parts store stuff, rather same as GM used in that era
