Great 4 flat to 7 pole blade dual outlet adapter.

Our new to us tow vehicle has LED lights and towing harness receptacle was 7 pole . My RV is 4 flat and I needed to adapt to the 7 pole system. The Nilight dual output adapter now allows me a choice of 4 wire flat and 7 pole blade connector for my jeep. Easy to install and fasteners included. Walmart Plus membership provides Free shipping making delivery to my door fast and low cost for Nilight dual output high quality adapter.
