• Will Trailer Connector PK11893 Work for a 2005 2005 GMC Sierra 1500
  
• One thing you might want to check is if your factory connector and your trailer wiring is still grounded well. Follow the ground wire from the plug and back and make sure that it is still firmly grounded, and that no pinched or exposed points are touching metal.

• Installing Third Brake Light and Dome Light into Truck Bed Cap
  
• If you will take a look at the wiring harness up above the spare tire, you should find the connector that the 7-way plugs into. If you trace the loom back just a bit, you will find a light blue wire that is used for the 3rd brake light for your truck cap. If you will follow the provided link, see Step 3 figure B.

• You are going to want to find the Center High Mount Stop Light wire for the brake light on the truck cap on your 2011 Chevy Silverado. This wire is bundled with the brake controller wiring located under the dash, and held together with tape and a tag that lists the wiring functions. The wire you are looking for is orange and will have a tag on it labeled CHMSL.

• Adding a 7-Way Trailer Connector to a 2010 Ford F-150 with Factory Installed 4-Way Flat Connector
  
• To convert the factory 4-Way flat trailer connector on the back of your 2010 Ford F-150, you will need Adapter 4 Pole to 7 Pole and 4 Pole, # 37185. You will plug the factory 4-Way into the back of the adapter and hardwire the remaining 4 wires. The white wire gets grounded to the vehicle frame. The blue wire on the adapter carries the brake controller output voltage, and the black adapter wire carries the 12-volt accessory voltage for any trailer mounted accessories that might need power.

• Troubleshooting Right Side Trailer Lights Not Working, Left Side Working Correctly
  
• Most trailer wiring problems are the result of a bad ground. What I would do is start with the connectors. Maker sure the connectors on both the trailer side and vehicle side are free of dirt and corrosion and that they are properly grounded. Next, I would move on to testing the vehicle side connector using a circuit tester like # 3808. Since the right side is not working, you will want to test the pins of the connector for right turn and brake. If looking at the face of the connector, it is

• Adding a 7-Way Blade Style Trailer Connector to a 2010 Chevy Silverado
  
• The 2010 Chevy Silverado could have fuses or relays that will need to be added in order to make the 7-Way trailer connector at the rear of the vehicle functional. You can check the fuse/relay legend on the inside of the power distribution box lid to see what fuses or relays are needed, or find the information in your vehicle owners manual. The correct replacement 7-Way trailer connector for your truck is the Twist-in, 7-Pole, RV-Style Trailer Connector, # PK11916. I have included a link to an

• Running a 12 Volt Trailer Connection Circuit on a 2007 GMC Classic Body Style with a Diesel Engine
  
• There is a power distribution box under the hood of the 2007 GMC Sierra that has two power posts that can be used for power to a brake controller and 12 volt power to the 7-Way RV connector at the rear of the vehicle. If your truck is equipped with a factory 7-Way and the 12 volt power circuit is not functioning you will need to check the 40 amp fuse nearest the forward most power post in the power distribution box. See photo at right. If you do not have a factory 7-Way on your vehicle or

• How to Wire a 7-Way Trailer Connector on a 1994 Chevrolet C/K Pickup
  
• To wire a 7-Way trailer connector at the rear of your 1994 Chevy pickup, you will need to start with a working 4-way connector, item # 118315, if your truck is not already equipped with one.

• Wiring Third Brake Lamp and Dome Light in Camper Shell on 2005 Chevy Silverado.
  
• The main trailer wiring harness is located under the truck bed, usually above the spare tire. There is usually a socket for your trailer connector to plug into, but if you peel back the wire loom you will find a light blue wire further up in the wiring harness that is intended for use for a third brake lamp on a camper shell. The dome lamp should be wired into a 12 volt power source and should have a toggle switch installed on the circuit. Probably the easiest method would be to use the runni

• 2005 Chevy Silverado 12 Volt Trailer Battery Wire for a 7-Way RV Connector
  
• In the under hood accessory fuse block there are two power posts on the engine side of the block. The post closest to the front of the truck should have a wire connected to it that runs back to the factory trailer connector and provides 12 volt power at the 1:00 position as you have stated. If there is not a wire present at this location, you may need to run a 10 gauge wire and splice it into the black wire at the back of the vehicle to provide power. If the wire is there, you should check th

• 7-Way Trailer Wiring Connector for a 2002 Chevy Silverado 1500 with Factory Tow Package
  
• First I would need to know how your 7-Way connector is different than newer models. Is if pinned out differently (the pin functions are in different locations between the years) or is it that it connects to the vehicle differently? If it is the latter, you can use the Pigtail Wiring Harness, # PK11998, with Hopkins Wiring, # HM4097 or # PK11893 You would just need to wire in the bare wire ends of the pigtail to the truck wiring by function.

• When Truck With 6-Way Connector is Put in Reverse the Trailer Brakes Lock Up
  
• Are you certain that you have the 6-way connector, like part # PK12720 with the 6 round pins? Or do you have the 7-way connector like part # PK11893 that features 6 blade-type pins with one connector in the center? The two can sometimes be confused. There are two possible reasons why the brakes are locking up on the trailer. If you have a surge or hydraulic coupler on the trailer, such as those typically found on boat trailers, the hydraulic brakes will lock up when the vehicle reverses unles

• Trailer Running Lights Not Working When Using a 7-Way to 4-Way Adapter
  
• It sounds like you have a 7-Way and are using a 7 to 4-Way adapter because the trailer has a 4-Way flat. If the running lights are not working with this set up, the first thing you will want to do is use a circuit tester, like # 3808 if needed, and test the vehicle side connector with no adapter installed in it. If the running light circuit is not working at the connector you know there is a problem on the vehicle side and you will need to trace the wiring from the trailer connector to deter

• Center High Mount Stop Light (CHMSL) Location on a 2006 Chevy Silverado for a Third Brake Light
  
• The 2006 Chevy Silverado will have the same wiring situation as a 2005. Locate the wire loom under the truck and above the spare tire. Like the question and answer you have referenced states, if you cut back the loom often times there will be 2 additional wires. The Light Blue wire provides a lead for a camper shell brake light. The other, a Light Green wire, is for the reverse lights. To make sure you have found the correct wires, use a circuit tester like # 3808 to test the wires.

• 12 Volt Power to 7-Way Trailer Connector Not Working on a 2004 Chevy Silverado
  
• If your 2004 Chevrolet Silverado has the factory tow package wiring that utilizes the # PK11893 style trailer connector, the first thing I would check is the tow package fuses in the power distribution box under the hood. You should find a legend under the lid of the box that details where the fuses are. Check to see if the fuse for the 7-Way 12 volt power is not installed in the correct location or is blown. Replace or insert a fuse as needed using the proper amperage fuse listed on the lid.
