Truck-Lite 88751 – 88 Series, 7 Plug, 744 in. Main Cable Harness, W/ Center Turn Breakout, 8, 10, 12 Gauge, Female 7 Pole Plug, Female .180 Bullet Terminal, Ring Terminal
Upgrade your commercial trailer's primary power distribution network with the severe-duty performance of the Truck-Lite 88751 88 Series 744-Inch Main Cable Harness. Engineered as an all-in-one electrical backbone for modern long-haul semi-trailers, drop-decks, and logistics fleets, this rugged 7-conductor, 7-plug main cable spans an expansive 744 inches (62 feet) in standard stocked length. Running seamlessly from the front nose box along the entire length of your vehicle’s chassis, it eliminates complex field splicing and dramatically reduces your dependence on vulnerable external junction boxes.
The standout capability of the Truck-Lite 88751 is its integrated Center Turn Breakout. This mid-chassis infrastructure allows for the quick, weatherproof connection of side turn signals and mid-ship marker arrays directly from the main feed. To support advanced electrical systems and auxiliary loads, its core features a heavy-duty, multi-gauge copper wiring layout combining thick 8 AWG, 10 AWG, and 12 AWG lines to eliminate voltage drop over long distances. Terminating with a molded female 7-pole plug and female .180 bullet connections on one end, and robust ring terminals on the other, this harness delivers an airtight, moisture-proof barrier that isolates internal circuitry from road salts, chemicals, and extreme highway vibration.
