4 and 5 Pole Trailer End Connectors

Expert Reply:

We have trailer end connectors in both 4 and 5 pole configurations. Also, we do carry covers that can be added to 4 pole connectors and boxes that can be mounted on the trailer to store connectors in. Cover number 30512 has an LED tester on it. We also have circuit testers that can be put in line with the vehicle and trailer or just plugged into the vehicle. The 5 way circuit tester, 20115, is an in-line model and should work for both 4 and 5 pole connectors. I have posted links below for your convenience.
