Buying Guide: Trailer Wiring Test Adapters

Converting Between Connector Types
This adapter is made for jobs where the vehicle side uses a 7 blade connector and the trailer end uses a 4/5 flat connector. Check both connectors before you order so you know the adapter matches your setup. Measure or count the blades and flats on your old part if you are unsure.

Checking Wiring With the LED Lights
The integrated LED lights help you see whether the wiring is working during testing. Follow your vehicle or trailer manual for the correct test procedure. Keep the included dust cover on the adapter when it is not in use.
