Item #9338-74

ADAPTER - 7 WAY ROUND TO 4 WAY FLAT

Product Description


Converts a 7 way socket to a 4 way flat

Most towing vehicles utilize a 7 way trailer plug to connect the lighting to a trailer or towed vehicle. But many smaller trailers or towables utilize a standard 4 way flat molded plug. The 9338-74 plugs into a 7 way socket. The back of the 9338-74 is designed to plug in a 4 way flat.

This is the easy way to connect between 7 way and 4 way wiring systems. It's Plug 'n Play. No tools required. No stripping wires. No connecting to terminals that are far too small to see.

The 9338-74 features:

  • Wired to standard 7 way and 4 way wiring codes
  • Plug and play — no wiring knowledge required
  • Durable ABS housing
  • No tools required
