Genuine Holden VZ Commodore LS1 5.7L V8 AUTO Engine Wiring Harness - Used - 92178224

Genuine Holden/GM automatic engine wiring harness, part number 92178224, removed from a VZ Commodore 5.7L LS1 V8. Complete loom with firewall bulkhead connector and both PCM plugs. Date coded K04.

Automatic only

This is the auto (4L60E) loom. It carries the transmission control circuits the manual loom does not have. If you are running a T56 manual you want the manual harness — this one will need rewiring to suit.

Identify it correctly

This is the blue/green PCM loom — the drive-by-wire P59 setup used on VZ. If your car has the red/blue PCM connectors, you have the earlier VT–VY P01 loom and this is not the right harness. Check your plug colours before ordering.

Fitment

• Holden VZ Commodore, Ute, Wagon, Crewman — 5.7L LS1 automatic

LS conversions

A complete factory LS1 engine loom is the starting point for any LS swap, and the auto version is the one most people want because the 4L60E wiring is already there. Everything is included — injectors, coils, sensors, MAF, knock, cam and crank, oxygen sensors, alternator and starter circuits — all in one genuine GM harness. Far better value than piecing a loom together, and it can be stripped back and shortened for a standalone conversion into a 4WD, older Holden or anything else running a Gen III.
