Multi-Tow Connector for RV and Trailer

This Bluarc Electronics connector combines a 7-blade round and a 4-flat plug in one housing. It supplies power and braking for an RV or runs tail lights and turn signals on a trailer. The kit includes a powder-coated mounting bracket and stainless steel hardware for a direct bolt-on fit. Some minor modifications may be needed on certain vehicles.

Weatherproof Lid and Corrosion-Resistant Terminals

A lid that opens 180 degrees on an oversized hinge seals the pins against water and road grime. Nickel-coated terminals and stainless steel fasteners resist corrosion over long service life. The heavy-duty OEM-style connectors are built to handle the electrical load of lighting and brake circuits without overheating.

Included Bracket and Hardware Simplify Installation

The supplied mounting bracket and stainless steel hardware let you secure the unit to a receiver or bumper without sourcing extra parts. Nickel-coated pins maintain low contact resistance so signals stay clean. The package replaces Hopkins 40950 and carries a five-year warranty against defects.

Questions about this item

How do I install the Bluarc Multi-Tow connector and which step is often missed?

Mount the powder-coated bracket with the included stainless-steel hardware, then plug the OEM connectors into the vehicle harness; the step often missed is tightening the bracket bolts to the specified torque so the 180-degree lid aligns and seals correctly.

What maintenance will the Bluarc Multi-Tow connector need over time?

Inspect the nickel-coated terminals and oversized hinge annually; clean any corrosion with electrical-contact cleaner and apply dielectric grease, and replace the lid gasket if it shows cracking to maintain the weatherproof seal.

What is the first limit I will hit when towing continuously with the Bluarc Multi-Tow connector?

The 180-degree lid hinge is the first component to show wear under sustained vibration and repeated opening cycles; lubricate the hinge pins regularly to prevent binding and premature fatigue.
