Planning to put the Holley Terminator X system in your Truck?

Installing a Diesel? Carburetor? FiTech? Megasquirt? AEM? Haltech? Honda Engine? 2JZ?

The CPW Vehicle Integration Harness will take the headache out of keeping your stock gauges and other vehicle functions with your swap.

Our typical configuration for this harness keeps the stock truck’s ECM in the original location near the battery under the hood.

Custom orders can be built if your installation does not fall under the above selections.

All NBS Vehicle Integration harnesses include wiring for A/C, Starter, factory gauges, and ABS. All factory functions of the truck can be retained with this product.

This harness does not contain any engine control functions.

The Stock truck ECM will need to be retained to make use of all the functions provided in this harness.

Vehicle Integration Harness for NBS 99-07 (GMT800) GM Trucks and SUVs
Must have rectangular “bolt-in” style fuse box connector for engine harness, not hardwired under hood fuse box.
P/N (Park/Neutral) Selection switch on driver’s side of 4 speed transmissions is either a 1 connector style or 2 connector style.

The CPW Vehicle Integration Harness is intended as a general purpose harness that will allow you to install any type of engine or engine control system in your vehicle, and not have to worry about tracking down the wires in the truck needed to maintain function of the stock gauges, starter, A/C, Fuel pump, etc.

This harness is intended to plug in to the original ECU mounted in it’s stock location on the driver’s side front corner of the engine bay.
If the ECU was from a V6 and you have swapped to a V8, the V6 ECU will need to be reprogrammed to a V8 so it will read the crank sensor from the new V8 engine.
If the new engine being installed is a 58x engine, you will need a Lingenfelter TRG-002 module to convert the 58x crank signal to a 24x crank signal in order for it to work with the NBS truck ECU

This system includes wiring for:

  • Body connections with power and grounds for vehicle fuse box and interior
  • Factory Fuel Pump relay control
  • Speedometer control
  • Tachometer control
  • Oil Pressure gauge
  • Coolant Temp gauge
  • Fuel Level gauge
  • Check Engine light
  • Gear Indicator (Select 1 or 2 connector Park/Neutral safety switch in menu, i.e. PRNDL switch on side of transmission)
  • A/C (Including IAC Kick and A/C interrupt for Holley interface)
  • Starter
  • ABS
  • Brake Switch signal
  • Backup Lights
  • Option to include HD Fan module which include integration with A/C function.

* The wiring to make these systems function is provided, but if your new ECU and/or engine does not provide the proper signals to the provided wiring, then there is no guarantee these functions can be maintained.
