Question:
I have a Hoppy- Older 5 wire 1 is red to 4 wire trailer harness. My question is there a diode in the flat plastic piece to prevent feedback to rig when connected?

Expert Reply:
Typically trailer connectors will not have any diodes to prevent feedback going to the tow vehicle from the trailer. Your trailer wiring will typically have a fuse or other circuitry to prevent damage to the vehicle in the event of electrical feedback. We do carry a single wire Diode # RM-690 if you wish to install these and prevent feedback on your tow vehicle wiring.
