Expert Answers about Wiring


  • Brake Controller Wiring for a 2007 Chevrolet Suburban
  • The 2007 Suburban does not require a wiring adapter. The tow package wiring is easily accessible and would wire directly to the brake controller. The wiring is located above the emergency brake pedal, and is taped to a wiring harness. Look for a white tag hanging off of the wiring. The four wires are red, dark blue, light blue and white. The red tow package wire connects to the black wire on the controller, the dark blue tow package wire connects to the blue brake controller wire, the light...

  • Trailer Wiring Harness for 2007 Ford Mustang
  • I'd recommend the # 18252, from Draw-Tite. To install, you'd use the included circuit tester to probe the wiring harnesses behind the taillight assemblies. Beginning on the driver's side, have a helper turn on the left turn signal, and use the tester to probe the wires until you find the one that makes the light on the tester blink. Tap the yellow wire into that circuit. Ground the white wire to the body of the vehicle, using an existing ground. Turn on the running lights, probe the wires...

  • Availability of Plug-and-Play Trailer Wiring Harness for 2001 Buick LeSabre
  • There isn't a plug and play option available for the 2001 Buick LeSabre, most likely due to the age of the vehicle and the fact that it's not frequently used to tow. However, there is an available hardwire option. You can use part # C59496, which would wire directly into the wiring harness that feeds your taillights. The best place to tap into your taillight wiring is directly behind the taillight assemblies. Use the included tester to probe the wires feeding the taillights. Have a helper...

  • Brake Controller Wiring Harness for 2008 Chevrolet Silverado Pickup
  • On your 2008 Silverado there is not a wire connector to plug in a brake controller wiring harness but there is a bundle of wires under the dash with a white tag on it to help you identify the wires for the brake controller. This bundle will contain a thick blue wire also. Once you have the wire bundle located you will have to hard wire the brake controller to these wires. The thick blue wire on the truck goes to the blue wire on the brake controller, the light blue wire with the white stripe...

  • Do You Have a 4-Way Flat Trailer Connector Which Has 5 Wires For Connecting to Trailer Wiring?
  • The only way we carry 4 flat trailer connectors which have 5 wires is on an entire trailer harness like the 20' # A20WB. This has the single yellow, green, and white wires with 2 brown wires. You can simply cut off the unneeded wiring and wire to your trailer wiring. You can still use a regular 4-Flat Connector # HM38134 and wire the 2 brown wires on your trailer to the single brown wire on the harness. This is an upgraded connector with easy pull connector and additional sheathing to protect...

However, there is an available hardwire option that'll work great for you. You can use part # C59496, which would wire directly into the wiring harnesses that feed your taillights.

  • Troubleshooting Trailer Wiring Not Lighting Up After Rewiring Trailer
  • If your RV wiring doesn't want to power the lights that means the issue is either the ground or the power since you have verified the lights work. You would want to use a circuit tester like part # PTW2993 to test the wires of the trailer with the correct taillight function on to determine which is the power wire and wire it accordingly to the lights of your trailer. If that still doesn't activate the light then the issue is the ground wire. In that case you need to improve the ground...

  • Wiring Adapter To Convert 13 Pin European Trailer Connector to 5-Way Flat Or 7-Way Blade Connection
  • You are going to have to create your own wiring harness as when I spoke to Thule they do not make a conversion kit for what you are needing. You will need a Curt 2 to 3 Wire Tail Light Converter # C56196 and a either a Hopkins Endurance 5-Way Flat Trailer Connector # HM47910 or a Hopkins 7-Pole Round Connector # H20042. I was unable to locate the exact color wiring used with your 8-pin connector, so I have included the chart that can be used to identify each of the wires on your Thule...

  • Installation of a 7-Way Connector On a 2010 Chevrolet Silverado With 7 Bare Wires and No Plug
  • To get a 7-Way connector at the rear of your 2010 Chevrolet Silverado I would use a circuit tester like part # PTW2993 and test the 7 bare wires for function. Then, use the Pollak 4 Foot Pigtail Wiring Harness, part # PK11998, to connect to the 7 bare wires by function using the included butt connectors. I would not connect them by colors because the colors will not always match the same function. After the wiring harness is attached correctly to your functioning bare wires on the vehicle...

  • Availability of Brake Controller Wiring for a 2010 Nissa Xterra with Factory Tow Package
  • Currently, there is no wiring harness made for the 2010 Nissan Xterra with a factory tow package. If it is anything like the 2010 Nissan Titan, there should be a factory harness located underneath and left of the steering column, taped to another harness near the emergency brake pedal. It is a 6-pin connector that mates with the # 3050-P brake control wiring adapter. I recommend checking ahead of time to see if the harness is there. If not, you will need to hardwire the brake controller...

  • Do you Have 5 Strand Wire for my Livestock Trailer.
  • I do not offer a 5 wire. Typically what we do here in this case is to use the Deka Wire Jacketed 7-Wire part # DW04914-1 and not use two of the wires. In your case they just didn't need the full 7 way function. Possibly eliminated the reverse wire and the power wire assuming the trailer has brakes on it. Leaving you with ground, taillights, left turn and brake, right turn and brake and the brake power wire.

  • Availability of 4-Way Wishbone Wiring Harness with Shorter Wire Lead
  • The wishbone harness with the shortest amount of wire lead has 20 feet of wire and a 30 inch ground wire, the Optronics 20 Foot Wishbone 4-Way Trailer Wiring Harness # A20WB. I wish we had a shorter option for you but our manufacturers don't offer a wishbone harness with a shorter lead. I double checked with Optronics and the 20 ft lead is the shortest they offer with a wishbone harness. If you'd rather use a connector with a shorter lead, the connector with a lead closest to the 18 inches...

  • What Wiring to Use to Install Electric Trailer Brakes
  • Trailer axles do sometimes include a wire for an electric trailer brake circuit to make it easier to route power to each of the brake assemblies. We have suitable 10-gauge brake circuit wiring, part # 10-1-1, that can be ordered by the foot. This wire has blue insulation which is the color usually associated with trailer brake wiring. Electric trailer brakes use a 2-wire hookup. Either wire from the brake can be used as ground or hot; since these wires are non-polarized it does not matter...

  • Are Tail Light Connectors Only Available By Themselves for Trailer Wiring on a 2013 Ford Escape
  • The connectors from any trailer wiring harness are not available by themselves. You could buy the harness and cut them off but if you were to buy it you might as well install that one and return the hardwire harness to the dealer. Or I could help you install the hardwire harness. It is actually pretty easy. You just need a circuit tester such as # PTW2993 to test the vehicle tail light wiring. On the driver side you will need to find the left turn signal wire and the running light wire....

  • How to Wire Third Brake Light on Camper Shell
  • Yes we do have a logic module that will work to wire your third brake light on your camper shell, part # PP20-702 the Pacer Performance 3rd Brake Light Logic Module. The third brake light needs to have a brake signal only, and if you are tapping into your trailer wiring, or tail lights wiring the turn and brake signals will be combined. The logic module filters out the unwanted turn signal inputs. This prevents the third brake light from flashing when you apply your turn signal. The...
