Holden VZ Commodore LS1 5.7L V8 Automatic Engine Wiring Loom + P59 ECU & TAC Module – 92178224

Used genuine Holden/GM VZ Commodore LS1 5.7L V8 automatic engine wiring loom complete with Delphi P59 ECU and electronic throttle/TAC control module.

This is a complete second-hand engine and automatic transmission wiring package removed from a VZ LS1 application. It includes the matching P59 ECU and genuine Holden/GM throttle control module, making it well suited to replacement, conversion and LS swap applications where the correct VZ LS1 automatic wiring configuration is required.

The loom has been professionally stripped and re-wrapped in heavy-duty automotive wiring harness tape and modified to allow the ECU to be mounted inside the cabin rather than in the original VZ passenger-side front guard/engine-bay location.

The wiring remains flexible and presents very well considering its age. Connectors are intact and in good condition with no obvious hardened or cracked wiring. Please inspect the supplied photographs carefully as this is the actual used loom and ECU package being sold.

Condition

This is a used second-hand component package, not a new replacement wiring harness. Normal marks, discolouration and other signs of age/use are present. The photographs form part of the product description and show the actual item supplied.

Due to the age of these vehicles and the possibility of modifications, conversions and component changes over their lifetime, please compare the part numbers, ECU connector configuration and photographs with your application before purchasing. Professional installation and final calibration/configuration may be required depending on the vehicle.
