Trailer maker East Manufacturing announced that the Truck-Lite 99 Series wiring harness will be standard on all new East BST, BST II, MMX and Narrow Neck flatbed trailers, starting Feb. 1.

The Truck-Lite 99 Series has been designed as a closed system by integrating a molded plug with two sealing surfaces, rather than just one. This new two-seal plug keeps moisture and debris out of the plug, guarding against corrosion.

The 99 Series uses a clamp, also serving as the mounting bracket, that wraps around the width of the plug to ensure that the connection is secure. Typical harness clamps only wrap around the junction itself so the wider clamp holds the joint more securely, resulting in a more reliable connection, according to the company.

The trapezoid-shaped connection is designed to make installation quicker and easier by ensuring proper pin alignment and a positive lock. With round harness cable connectors, it is sometimes difficult for an operator to be assured of a positive pin connection from underneath the trailer, according to East.

“Truck-Lite’s attention to connection and corrosion issues will provide our customers with a more reliable and secure connection, which coincides with our mission to provide reliable trailer products for our customers," said Dave de Poincy, president of East.
