Wacker Neuson 5100029257 Wiring Harness, Control Module Auto Start

The Wacker Neuson Wiring Harness, Control Module Auto Start is a genuine OEM component designed for the LTV6K and LTV8K light towers. Sourced directly from Wacker Neuson, this harness delivers the exact connector layout, wire gauge, and routing configuration required by the auto start control module on these machines. It is a direct-fit replacement that integrates cleanly into the existing electrical architecture of the LTV series, ensuring the control module communicates correctly with the generator and lighting systems. If you are troubleshooting an auto start fault or replacing damaged wiring on your LTV6K or LTV8K, part number is the correct OEM solution.

Key Features

• Correct Conductor Spec and Connector Pinout — Each wire is matched to OEM gauge and termination standards, ensuring accurate signal transmission between the auto start control module and the machine's electrical system.
• Genuine OEM Part — Supplied by Wacker Neuson, this harness meets the same build standard as the original unit installed at the factory — no guesswork on compatibility or connector fit.
• LTV Series Fitment — Confirmed fit for LTV6K and LTV8K light towers; verify your model number against part 5100029257 before ordering.
• Auto Start System Integrity — A damaged or corroded wiring harness is a leading cause of auto start failure on light towers. Replacing it with the correct OEM harness restores reliable automated generator start/stop operation.
• Electrical Safety Compliance — Using the correct OEM harness prevents undersized or mismatched wiring that can cause shorts, control module damage, or unintended generator behavior on the jobsite.

The wiring harness for the control module auto start system is the electrical backbone that connects the auto start module to the generator's ignition, run, and shutdown circuits. It carries the low-voltage signals that tell the generator when to start, run, and stop based on input from the control module — whether triggered by a timer, a load sensor, or a manual command. When this harness degrades through abrasion, heat exposure, or connector corrosion, the auto start system can behave erratically, fail to start the generator entirely, or prevent clean shutdown, leaving the light tower inoperable or running unattended longer than intended.
