Product Details

The Sierra TC50000 is an 18-inch trailer wiring extension harness and adapter that bridges the gap between mismatched tow vehicle and trailer connector configurations. Designed for marine, RV, and general trailering applications, this adapter allows a tow vehicle equipped with a 4-pole, 6-pole, or 7-pole RV-style blade socket to connect to a trailer with a 5-pole flat plug — eliminating the need for rewiring or permanent modifications.

Key Features:

  • Converts a 7-pole RV-style blade vehicle socket to a 5-pole flat trailer plug
  • 18-inch extension harness provides flexible reach between vehicle and trailer connections
  • Compatible with tow vehicles equipped with 4-pole, 6-pole, or 7-pole sockets
  • Constructed with a quality molded plastic connector for durability and corrosion resistance
  • Compact design stores conveniently in a glove box when not in use
  • Ideal for marine trailering, RV, and powersports towing applications

The Sierra TC50000 is a practical, no-hassle solution for boaters and trailer owners who need a reliable wiring connection without cutting or splicing into existing harnesses.

great price and quick shipping !!!

Had what I need when I needed it. Thanks

thanks

good

I ordered the Dee Zee truck box rails and the price was the best on the net after searching. Also, fast shipping. I would recomend this site.

Good company, good prices and great staff.

My truck bed cover arrived today. Everything looks okay. Looking forward to installing it this weekend. <br> Thanks for the quick shipping.

Your website said that these would not fit my vehicle. However, every other site says they do, including the manufacturer's website.

Best prices on the Net with easy payment and shipping. I will definitely use them again!

Autoplicity has done everything right. no problems here. would buy from again.

Great prices & fast shipping.

Web interface seems a little clunky-----a lot of seemingly unnecessary scrolling.
