• Which Nuts Needed to Complete Brake Controller Connections At Fuse Box on 2007 GMC Sierra New Body
  There are two threaded studs on the front of the power distribution box (closest to the front bumper) that will need to have the 12-V feed to the trailer connector and the power feed to the brake controller connected if they aren't already. As you've likely found, GM decided to save the $ 0.25 it would have cost them to supply the nuts needed to secure the wires to the studs. Both studs are different sizes, you'll need a M6-1.0 nut which we carry as part # 185916 and an M8-1.25 nut which...

  To install a 7-Way wiring connector at the rear of your 2001 Chevrolet Silverado without a factory 7-Way or a factory 4-Way connector, I recommend using the 7-Pole and 4-Pole Trailer Connector Socket and wiring harness, # HM40975-11998. You can the wire most of the circuits needed to the wiring harness that is located above the spare tire along the driver side frame rail.

• No Power On Trailer Battery Circuit In 7-Way on a 2005 Chevy Tahoe
  The first thing I will have you do is check the studs on your power distribution center (PDC) or otherwise known as the fuse box. These studs are to supply power to a brake controller (if equipped) or to the 7-way for 12 volt power. The issue we see is that many times they are not connected from the factory. The 12 volt power lead for the 7-way is located to the left of the power distribution center, taped to a wire harness under the power brake booster. In order to attach this you will...

• Activating 7-way Trailer Accessory Power Circuit on 1995 Chevy Sliverado
  The orange wire from the rudimentary tow package on the 1995 Silverado ends in the engine compartment, under the brake booster (see photo). There will be a coiled up piece of wire that is secured with electrical tape. Years of road crud is probably built up on the tape, which could make the wire difficult to find. Once you find it, you can either connect it to a inline circuit breaker like part # 9510 and run it to the positive battery terminal, or you can connect it to the power post on...

• Interior Trailer Lights Not Working When Connected to a 2011 GMC Sierra Denali
  The interior dome lights on your trailer likely run off of either a trailer mounted battery or directly off of the 12 volt circuit from the trailer connector (if it uses a 7-Way connector). If they connect to a battery then check to see if the battery is good, needs a charge, or needs to be replaced. To keep a trailer battery charged and maintained I recommend hooking it up to a CTEK battery charger, # CTEK56353, which will charge and recondition a battery. If the lights don't run off...

I'll link to an article that discusses this in depth, but I'd be happy to run through the gist of it here. Check fuse position 63 and 68, and make sure fuses are installed.

• 2008 Chevrolet Silverado 2500 12 Volt Trailer Towing Wire Connection Instructions
  Your 2008 Chevrolet Silverado is set up from the factory with trailer tow wiring, so I agree that wiring power wires from the battery is not the way that things should be done in your case. On the 2008 Chevrolet Silverado there are two wires under the hood that need to be connected to have power to the 7-Way trailer connector at the back of the vehicle and the brake controller wiring under the dash, see photo at right. These wires are connected to the two studs at the power distribution...

• Troubleshooting 7-Way Trailer Connector Does Not Have 12 Volt Power on a 2010 GMC Sierra
  The first thing you will want to check is the pin on the front of the 7-Way that is in the 11 o'clock position using a circuit tester like # PTW2993. If it is not showing a signal, then it could be that the 12-volt hot lead is not connected at the point under the hood. The wire you will need is red/black and has an eyelet connected to one end. It is coiled up under the master cylinder/brake booster assembly and must be connected to the under-hood fuse box. The battery charge wire will...

• Troubleshooting Tekonsha POD PowerTrac Brake Controller Installed on 2007 Silverado LTZ
  It sounds to me as if your controller is not getting sufficient 12-volt power to operate correctly. Try using a circuit tester like part # PTW2993 on the black power supply wire feeding the brake controller. I am guessing you will not see any power on this wire. The flickering you describe is from the slight amount of power reaching the controller through the red wire that serves as the input to the controller that tells it when the vehicle brakes are being applied. I suspect that the...

• Parts Needed To Install A Trailer Brake Controller On a 2010 Chevrolet Suburban LTZ.
  We do have many electric trailer brake controllers for your 2010 Chevrolet Suburban LTZ.
