Truck-Lite 50969 – 88 Series 14-Inch Main Cable Harness, 7-Wire, Male to Female 7-Pole Plugs

Ensure clean, heavy-duty electrical delivery across your fleet with the Truck-Lite 50969 88 Series Main Cable Harness. Measuring 14 inches in length, this premium 7-conductor round cable is engineered with robust 8, 10, and 12-gauge wiring to manage high-amperage demands without voltage drops. Complete with one integrated Male 7-Pole plug and one Female 7-Pole plug, it creates a secure, weather-resistant link for commercial vehicle and nose box connections.

When routing primary electrical power between truck tractors and trailers, choosing heavy-gauge, fleet-grade wiring is critical to preventing line resistance, voltage drops, and roadside lighting failures. The Truck-Lite 50969 88 Series 2-Plug Main Cable Harness provides an industrial, heavy-duty connection point built specifically to bridge nose box and primary harness gaps.

The 50969 is built using a rugged, round black cable housing that packs 7 color-coded copper conductors (Black, Blue, Brown, Green, Red, White, Yellow). To seamlessly support modern commercial trailer requirements—including power-hungry anti-lock braking systems (ABS) and auxiliary gear—this harness combines heavy-duty 8-gauge, 10-gauge, and 12-gauge wiring.

Equipped with a molded Male 7-Pole plug on one end and a matching Female 7-Pole plug on the other, this 14-inch jumper adapter creates a plug-and-play connection that cuts down on manual wire splicing and fleet installation downtime. Backed by Truck-Lite’s premium construction standards, this 88 Series harness handles severe vibration, grease exposure, and seasonal freezing without cracking.
