Expert Answers about GMC 12V Power Accessories


  • Recommended Vehicle 7-Way to 12v Plug Adapter
  • To turn the 7-way on your truck into a 12v power source you will want to use the Pollak 7-Way to 12 Volt Power Outlet Adapter item # PK11896. This will plug into a 7-Way on your vehicle and provide a 12V plug on the other end that can be used with 12V accessories. This adapter can handle a 20 to 30 amp power draw but the limiting factor will be if the 7-Way on your truck is rated high enough as well. You will want to check the fuse for the 12 volt circuit for the tow package trailer connector...

  • How Much 120 Volt Power Does The Converter # PD4645V Draw?
  • The Converter for Parallax/Magnetek or WFCO RV Power Centers # PD4645V is rated for 45 amps of 12 volt power with up to 610 watts of output power. This is roughly the same amount of input wattage or about 5.1 amps of 120 volt power at maximum draw. Since the power from the converter is mostly used for charging the 12 volt battery and supplying power to the 12 volt lights, slide motors, power awning, and any other 12 volt components on your trailer it will often only be pulling much less...

  • Powering Horse Trailer Lights w/ and w/out a Battery
  • I have a solution for you but the only way to power accessory lighting in your trailer through a 12v is to use an adapter like the Pollak 7-Way to 12 Volt Power Outlet Adapter item # PK11896. It sounds like you already have one of these. This will turn your 7-way connector into a 12v power source. Once you have a 12v connector on your 7-way you will want to purchase an adapter that has two male 12v ends. There isn't a 7-way trailer connector to a 12v male connector adapter. The reason there...

  • Solution to Activate 12 Volt Power Circuit of 7-Way on 2012 Ram 1500
  • Sometimes that circuit isn't active. The easy answer would be to run a length of 10 gauge wire like part # 10-1-1 through a breaker like the part # 9510 to the positive terminal of your truck battery. With some Ram trucks if trailer circuits have fuses blow the only way to reset it is to take it to a dealer which is frustrating.

  • Can Trailer Battery be Charged by 12 Volt Accessory Circuit of 7-Way
  • You are correct a wire ran from the 12 volt accessory circuit of you 7-way to the positive post of the battery will keep a maintenance charge on it. This will keep the battery topped off but would not bring a totally dead battery back to life. You would want to use 10 gauge wire like part # 10-1-1 for this.

  • What is the Wattage on the Opti-Brite 12v/24v LED Dome Light
  • I'll start off by saying that lumens is a measurement of the light that is given off by a particular light and not a measurement of energy usage. When it comes to determining the wattage, that is calculated by multiplying the amp draw multiplied by the voltage of the power supply (Formula is: Current (a) x Voltage (v) = Power (w)). The Opti-Brite 12v/24v LED Dome Light # ILL08COB uses 1.61 amps on 12.8v power and 0.8 amps on 24v power. When you use these numbers, on a 12.8v power supply...

The mounting holes are spaced 3.94" apart side-to-side and top-to-bottom.

  • What Wire Gauge Needed for 12V Trailer Power Feed
  • A 12V trailer power circuit will typically be wired with 12-gauge wire, part # 12-1-1, but certainly there is no harm in using heavier 10-gauge wire # 10-1-1. If one tow vehicle is longer than another, our installers may opt to use the heavier gauge wiring than they would for a physically shorter vehicle. When in doubt you can always use 10-gauge.
