High quality product used to replace a lower quality harness installed by the RV manufacturer. I was having intermittent “check trailer brakes” on my dashboard display. Suspected a wiring issue. Founded crashed insulation on the blue trailer brake wires in the travel trailer junction box for all functions. Repair complete and no repeated error messages. The LED system status lights provide instant information that the truck is providing al proper electrical signals and power for the travel trailer. 663025

90 day warranty and I didn’t use it in those 90 days. Truck keep getting error of trailer disconnect. Traced it to no connectivity on one wire. I cut the plug off and put a new one and never looked back. 856326

Product arrived in good condition. I'm certain it's going to work perfectly. The plug is a heavy rubber compound with the LEDS molded into the handle. Great looking and feeling over all. I got the 8' wire to replace the travel trailer cord that got pinched. I chose this style because I didn't have a volt meter with me and ended up spending an extra 2 hours to figure out the repair I made was good and that I had blown the fuses. The LEDs will save me if it happens again 772240

Love it. Debated weather another $15 for the LEDs on the plug was worth it. Spend the money as it is well worth it for trouble shooting. I did and glad I did. 543083

Absolutely love this harness! I kept getting the trailer disconnected message from my TT. This solved it and the LEDs show you what power is beeing sent from the truck. I gave 4 stars because there should be a diode because the AX light stays on even when it is unhooked from the truck and will not show if the truck is charging the TT because of the TT battery. 542889

Ask the Experts about this Hopkins Wiring

  • Adding a New 7-Way Trailer Connector and Wiring to a Car Hauler Trailer
    You will likely need some additional wire to reach the lights when installing 7-Way connector # HM20087. If you just want 4-wire you can use # DW04923-1, sold by the foot, or # 16-4B-1, also sold by the foot. You will also need some butt connectors such as heat shrink version # DW05744-5. If you want all 7-wires you can use # DW04914-1 which is sold by the foot as well. Another option is a 7-Way that is considerably longer, # 50-67-008, which at 22 feet long is more than twice the length...

  • Installation of 7-Way Trailer Wiring When Colors Dont Match
    If you have connected your Hopkins 7-Way RV Style Connector w/ Molded Cable and LED Test Lights - Trailer End - 8' Long # HM20087 incorrectly, you will not cause any damage to your system as long as the ground connection installed correctly. If the ground is in the wrong location you have the potential to blow fuses, damage lights, etc. If the ground is in the correct location, then the wiring will work and you just will need to match functions. If you are unsure of the ground connection,...

  • Can LED Test Lights on Hopkins 7-Way RV Style Connector HM20087 Cause Battery Drain
    LED lights, including LED test lights that can be built into trailer wiring, use so very little power that you do not need to be concerned about depleting your battery. It would take many, many months of continuous draw (without ever running the truck to charge the battery) for such an item as the Hopkins 7-Way RV Style Connector # HM20087 to cause any issue with battery drain in your 2012 Ford F-150.

  • Recommend Trailer Wiring Connectors To Test Functions Of 7-Way
    It sounds like you are looking for the LED testers integrated into your wiring. If you want the trailer side 7-way with LED, I recommend the Hopkins 7-Way RV Style Trailer Connector w/ LED Test Lights - Trailer End # HM48503. This will let you know if power is being received from the tow vehicle for each function to make testing and troubleshooting easy. This is already integrated in the Hopkins 7-Way RV Style Connector w/ Molded Cable and LED Test Lights - Trailer End - 8' Long # HM20087....
