- Trailer Tail Lights Go Out With Headlights On And When Brake Pedal is Pressed On 1993 Chevy 3500
- It sounds like you have a ground problem on the trailer. However, there also could be a problem on your tow vehicle.
We can isolate the problem to narrow the search a bit. Disconnect the trailer from the truck. Using a circuit tester, like part # 3808, test the 4-Way connector. Clip the tester to the truck frame as your ground, and test the brown, yellow and green wires to make sure they function properly. Brown is tail lights, yellow is left turn and brake, and green is right turn and brake.

- Powered and Non Powered Trailer Light Converter Wiring on 2000 Nissan Frontier - Lights Not Working-
- On this 2000 Nissan Frontier it sounds like it is a ground issue. On many of the import trucks it is hard to find a good ground on the vehicle. To test this you might try a jumper wire from the license plate ground wire to the ground on the trailer harness. If that works then just use the license plate ground wire connection as a permanent ground.

- How to Add a 7-Way Round Pin Trailer Connector to a 2011 Chevy Silverado with 7-Way Blade Connector
- Your 2011 Chevy Silverado has what is called a multitow trailer connector with a 4-Way flat and 7-Way blade style trailer connector. In order to convert the 7-Way portion to a 7-Way Round pin, all you will need is an adapter. We have one that would be perfect for you. Take a look at the Hopkins Adapter 7 Way Blade to 7 Way Round Pin, # 47595. All you will need to do is plug in the 7-Way blade end into your truck 7-Way.

- Low Voltage on Pollack 7-Pole Trailer Connector Right Turn Signal Pin on a 2002 Toyota Sienna
- On the back of the connector where the wires attach check for dirt and corrosion and clean any that you find. You may need a new connection there so cut the wire, strip off some of the insulation, and reconnect after cleaning the connector. Do this for any of the wires that appear to need it.
Also check the main ground from the connector to the vehicle. It should be attached to a clean and corrosion free bare metal surface. You can also try moving the ground to a different location on the fr

- Is it Better to Switch to a 7-Way Blade Style Trailer Connector Over a 7-Way Round Pin
- The 7-Way blade style trailer connector is the most common 7-Way in use at this time. It would be beneficial to switch to this style. However, if you already have a 7-Way round connector you can just use an adapter to go to a 7-Way blade style when needed. You can use # PK12-724.
If you want to go ahead and switch from the 7-Way round to the blade style I recommend a multi-tow connector, # HM48470, which has a 7-Way blade style, a 5-Way flat, and 4-Way flat. All you will need to do is remove

- Installation of Pollak 7-Way Round Pin Trailer Connector # PK11720 on 2011 Chevrolet Silverado 3500
- To determine the function of the red wire on your 2011 Chevy Silverado 3500 HD I would recommend to use a circuit tester like the Quickee Tester, part # 3808, to test the wire. Since the vehicle manufacturers can change the factory wire colors over the years it is hard to know the function of the wire without testing it. Sometimes the red wire would be for 12 volt power on the Silverado.
The 2011 Silverado will usually come with a factory wiring harness plug on the rear of the truck that will

- Availability of a 7-Way to 5-Way Flat Trailer Connector Adapter
- If your 7-Way has round pins like those in # PK11720 then it will require a little fabrication to make an adapter. But if you have the blade style like # PK12707 then you can use adapter # A75TB.
If you do have the round pins then you will need a trailer end 7-Pole round pin connector, # PK11700, and a 5-Way vehicle end, # HM47900. You would then just wire in the 5-Way wires to the 7-Pole round to match the functions used by the vehicle end connector.
