  • Can An Extension Be Used With The Roadmaster 12v Outlet Kit
  • It's totally normal to splice on some extra wire to the 12 Volt Outlet Kit # RM-9332 to get it to the battery so I would just use some 16 AWG # 16-1-1 and a butt connector # DW05744-10 instead of using the extension # RM-9331. The extension would technically work but just splicing in more wire is a bit cleaner of a setup.

  • Trailer Wiring Harness for 2008 Hummer H3 Alpha
  • If your Hummer has the tow package, you can use the Multi-Tow 7-Way and 4-Way Trailer Connector, part # 30955. This connector would plug into a socket located below the cargo area. This connector can accommodate either a 4 or a 7-way trailer connector. If your Hummer does not have the tow package, there is not plug and play type option available. The 4-Pole Hardwire Kit, part # 18252 would be your best bet. Installing this connector is pretty simple. Access the rear of your tail light...

  • What Wires Does a Brake Controller Wire to on a 2009 Hummer H3
  • It sounds as if you maybe haven't found the correct wires to install a brake controller like the Prodigy P3 part # 90195 in your 2009 Hummer H3. The colors should be red, light blue, dark blue, black, and brown. I attached a chart that shows where they would wire to the P3. The bundle is usually taped up in one of three places underneath the dash. Sometimes it is next to the center console by the gas pedal, sometimes it is above the emergency foot brake by the door and other times it...

  • Does Prodigy P3 Brake Controller for 2009 Hummer H3 Use a Wiring Harness
  • If you purchased your Prodigy P3 Trailer Brake Controller # 90195 new, it will have a wiring harness that comes with it that you will have to hardwire into your 2009 Hummer H3. Otherwise, if you are simply looking for a replacement harness for the controller it is the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller # 20127. I have added a link to a video review of that harness as well as the Prodigy P3 Trailer Brake Controller # 90195.

  • Installing a Brake Controller in a 2007 Hummer H3
  • Your 2007 Hummer H3 should have four or five blunt cut wires under the left side of the instrument panel to the left of the steering column. You should see a bundle that contains a red wire with a black stripe, a white wire, light blue wire with a white stripe, a dark blue wire and possibly an orange wire. The bundle could be above the emergency foot brake, behind the plastic kick panel or above the brake pedal. This bundle of wires is what is used to hook up the electrical lead wires...

  • How to Determine Functions of Brake Controller Harness on a 2008 Hummer H3
  • The best way to determine what functions each of those wires on your 2008 Hummer H3 carries is to use a circuit tester like part # PTW2992 and check to see what each wire does. I tried looking up what functions they might carry but the only thing that seemed to be consistent is that the orange wire has constant 12V power to it. You can verify this by connecting the circuit tester to that wire and seeing if it has constant power or not. The typical brake controller wiring pigtail has white,...

  • How to Install a Brake Controller on a 2008 Hummer H3
  • Brake controllers can be used with virtually any vehicle so there are not many vehicle specific instructions out there. Underneath your dash somewhere is a bundle of 4 or 5 wires Red, Light Blue, Black, Dark Blue and possibly Orange. The Orange wire will not be used. The bundle is usually taped up in one of three places underneath the dash.

  • Installation of Roadmaster Auto Battery Disconnect # RM-766 on 2009 Hummer H2 With 5-Way Connector
  • Since the battery must be disconnected when flat towing your 2009 Hummer H2 an option is to use the Roadmaster Auto Battery Disconnect, part #RM-766. The disconnect is activated by the taillight circuit from the tow vehicle. When the tow vehicle taillights are on, the solenoid is activated and the Hummer battery is automatically disconnected. The power from the taillight circuit that is not needed to keep the solenoid open is then routed to the Hummer battery helping to maintain the charge...

  • Installing a Tekonsha P2 Electric Trailer Brake Controller # 90885 on a 2004 Hummer H1
  • To install the Tekonsha P2 Brake Controller # 90885, in your 2004 Hummer H1, you will need to do a little hardwiring, but since you already have a functioning 7-Way trailer connector, there will not be too much work involved to get it installed and ready to tow. First, you will need enough wire # 10-1-1 to reach from the 7-Way trailer connector at the back of the H1 to the cab of the vehicle where you plan to mount the brake controller. This wire is sold in 1-foot increments. I recommend...

  • Installing a Tekonsha P2 Trailer Brake Controller on a 2010 Hummer H3T with Factory 7-Way Connector
  • Since your Hummer H3T came with a factory 7-Way, you will be able to find the tow package wiring under the dash of the vehicle. The wiring should be located to the right of the steering column, under the dash, behind the radio area. The wires should be labeled. You will splice the brake controller wiring to these wires. On the brake controller, white is ground, black is 12 volt power, blue is output to the trailer brakes, and red is input from the brake switch stop light wire. If there...

  • Installation of 3015-S Trailer Brake Controller Harness in 2003 Hummer H2
  • The Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - GM # 3015-S does match color for color if you have 12V power getting to the adapter. If you do not, then they specify that the red and black are reversed for functions in step 3. If you have power then you skip step 3 and move to step 4 which is matching color for color. I've highlighted this part to assist in the attached photo. The brake controller will have black for power input which will connect to the...

  • Installation Instructions for Prodigy P2 Brake Controller on a 2008 Hummer H3
  • I have attached the instructions that you are referring to for the Prodigy P2 # 90885 but they are no different than what you received with your unit.

If you have the factory 7-Way on your Hummer then you should find a bundle of wires up under the driver's side of your dash. You can test the wires with...
