Multiquip EE55622 Lights Harness 7-Pin

The Multiquip EE55622 Lights Harness 7-Pin is a genuine OEM wiring harness designed for MQ600H, MQ600HTB, and MQ600HTP trash pumps, as well as WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, and WT5HPSG water trailers. As a direct Multiquip OEM part, EE55622 is manufactured to the exact electrical specifications of the original harness, ensuring a clean, correct connection every time. This harness is a direct plug-in replacement — no splicing, improvising, or adapting required. If your trailer or pump lighting is intermittent, dead, or damaged at the connector, replacing it with the correct OEM harness restores full lighting function and keeps your equipment road and site legal.

Key Features

• OEM-Correct Wiring Specification — Matched conductor gauge, insulation rating, and pin configuration to the original Multiquip harness — no guesswork on compatibility.
• Standard 7-Pin Connector — Designed to interface directly with standard 7-pin trailer plugs, ensuring a secure, corrosion-resistant connection at the tow vehicle end.
• Broad Fitment Across Multiquip Lines — Confirmed fit for MQ600H, MQ600HTB, and MQ600HTP trash pumps, plus WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, and WT5HPSG water trailers.
• Full Lighting Circuit Integrity — Restores running lights, brake lights, and turn signals to proper operation — critical for towing compliance and on-road safety.
• Road and Site Safety Compliance — Trailer lighting is a legal requirement when towing on public roads; a failed or damaged harness puts you out of compliance and creates a hazard for other operators.

The lights harness on a tow-behind unit carries all electrical signals from the tow vehicle to the trailer's lighting system — running lights, brake lights, and turn signals. The 7-pin connector format supports the full range of lighting and auxiliary functions required for towable equipment. When the harness fails — whether through a broken wire, corroded pin, or damaged connector — lighting becomes intermittent or fails entirely, making the trailer unsafe and illegal to tow on public roads. Replacing the harness with the correct OEM part restores the full circuit and eliminates the failure point.
