• Tekonsha Primus IQ Trailer Brake Controller Shows PL Error Code on 2011 Cadillac Escalade
• On the GM tow package wiring under the dash of vehicles like your 2011 Cadillac Escalade, there are typically 5 wires: ground, 12 volt power, output to trailer brakes, input from stop light switch, and illumination. If you have the brake controller red wire connected to the illumination wire this may be causing the problem. It is also possible that there is a bad ground connection. You can test this by attaching the white brake controller wire to the negative battery terminal of a separate...

• Troubleshooting 4-Way Wire Harness installation On 2009 Cadillac SRX
• The wiring harnesses and kit, part # HM48895 and part # HM46155 you referenced in your question are not designed to be a fit for your 2009 Cadillac SRX. If you find that you have the correct wire harness for your SRX you can check the wiring to make sure all of the wires have been connected as the instructions state. Also, you will want to make sure the ground wire has been secured to a clean bare metal surface. Loose or corroded grounds can cause some of the same problems you described....

• Troubleshooting Wiring Harness On 2007 Cadillac SRX
• Any wiring harness can go bad for a variety of reasons whether it is a bad module, crimped or broken wires, or corrosion on the pins. You can troubleshoot a wiring harness to see if there is a problem by using a circuit tester like part # PTW2993. First, you want to make surer there is no corrosion in the trailer connector, and clean it is any is found. Then have someone sit in the driver seat and run through the functions while you test the trailer connector pins for function. If any...

• Brake Pedal Causing Turn Signals to Flash Briefly With Tail Light Converter 118158
• Thank you for your purchase of the Vehicle to Vehicle Tail Light Converter # 118158. Based on the scenario you mentioned, it does sound like there is likely backfeeding happening that is causing the turn signals to briefly flash when you hit the brakes. The best remedy for this would be what you mentioned, which is to use diodes, the Roadmaster Hy-Power Diodes # RM-792. I have added a link below to a video review for you to check out as well if you'd like.

• Troubleshooting B&W Companion 5th Wheel Hitch Not Releasing
• The B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter - Dual Jaw - 20,000 lbs # BWRVK3500 has a binding issue with your king pin. The cam action latching handle sounds like it isn't functioning correctly. If the head has been damaged, I recommend replacing it. If it isn't damaged and yet isn't functioning correctly, I recommend contacting the manufacturer about coverage under the limited lifetime warranty. If you need to replace the head unit, the Replacement Head Assembly...

• Troubleshooting Curt Trailer Brake Controller Installation On a 2014 Cadillac Escalade
• It looks like the Curt Custom Wiring Adapter # C51451 is only confirmed to fit the 2015-2022 Cadillac Escalade. With you connecting it to a 2014 Escalade it is likely going to a connection that is not for the brake controller. On the 2014 you should be using a Universal Wiring Adapter # C51515 since the wires are not terminated into a connector but only cut and sealed at the ends. Then you will be able to connect a brake controller like the Curt TriFlex # C24VV. I have linked an article...

• Troubleshooting Interior Dome Lights On an Enclosed Trailer Not Functioning
• Depending on how your 2011 Noe trailer was wired you will have a couple things to check. First the exterior running lights, brake lights and turn signals will run off different circuits than any interior dome lights. Typically with interior lights there will be a dedicated battery for the lights so they can still be operated when not connected to your tow vehicle. Otherwise they will likely just be connected to the auxiliary charge line circuit on the 7-way. A Test Light # PTW2993 can be...

• Turn and Brake Lights Do Not Work Using 6-Diode Kit and Converter for Towing a 2012 Cadillac SRX
• It sounds like you have a good grasp on the installation of the Roadmaster 6-Diode Universal Wiring Kit, # 154-792-118158, and you have already gone through a few troubleshooting steps, so I would recommend troubleshooting the converter box from the # 118158 wiring harness. Installing the # 118158 wiring harness at the front of your 2012 Cadillac SRX instead of closer to the taillights is not a problem. To troubleshoot the converter box of this wiring harness, I would first recommend...

• Troubleshooting Falcon All Terrain Tow Bar Arms Difficult to Slide In and Out
• I'm not sure what process you used to clean and lubricate your # RM-522, but I would soak the arms with degreaser and then move the arms in and out while rinsing them off with water. You can also use the Roadmaster Tow Bar Cleaner # RM-9932. After they are rinsed, dry the arms thoroughly and lubricate them with a dry silicone spray like the # RM-747. Assuming this was done, you need the Repair Kit for Roadmaster Falcon and Blackhawk All Terrain Tow Bars # RM910003-85. This should fix the...

• Troubleshooting No Propane Flow On Trailer with New Tank and New Regulator
• Yes. The pigtail could be the issue. I recommend replacing the pigtail with the MB Sturgis Propane Hose w/ Back Check - Type 1 x 1/4" MPT - 20" # 100473-20-MBS. There is an internal back-check on Type 1 fittings that could be the issue.

Thank you for your recent purchase of a hitch and related items along with this wiring harness. The exact components that constitute a factory tow package will vary among auto makers and can also vary among different vehicle models and model years. Sometimes wiring may be put in place at the factory but may not be connected at one or...

• Troubleshooting Trailer Wiring that All Lights Turn On When Headlights are On
• It sounds like the running light circuit of your trailer wiring is shorting out to the other wires of the trailer harness that you installed so that when you have the head lights on the power from the running light circuit is also being applied to the other circuits as well. I attached a couple help articles on troubleshooting for you to check out as well.

• Add-On LED Turn Signals are Hyper Flashing on a 2007 Cadillac SRX
• The hyper flashing might stop if you put them on all turn signal circuits, including the front ones. And it may not. Since this is a non-standard set up it will take some trial and error to determine what the problem might be. If you have the load resistors grounded to the same ground as the light I recommend moving it to its own ground location specifically to a clean and corrosion free bare metal surface with no paint or coating. If you have the resistors grounded separately already...

• Troubleshooting Transmission Fluid And Engine Coolant Mixing On 2003 Cadillac CTS
• Sorry to hear about the problems with your brother's 2003 Cadillac. The first thing you will want to do is have the transmission taken care of. I am not aware of a separate cooler for the transmission located under the intake manifold. Typically what is used is a line that runs from the transmission to the radiator. The radiator holds engine coolant and the transmission fluid line is run inside the radiator as well. The radiator cools both the engine coolant and the transmission fluid...

• Troubleshooting Prodigy Brake Controller that Flashes SH Code
• The error code you are reading indicates that there is a short circuit somewhere in the brake outupt circut on your trailer. Most likely, there is a pinched wire or at some point the wire insulation has cracked or been worn to the point where the copper wire is contacting the trailer frame or some other metal part. Start at the trailer connector, making sure that it's not corroded or damaged, then work your way back to the brake magnets, examining the wire as you go. The controller can...

• 2014 Cadillac Escalade Wont Start After Curt Brake Controller Installation
• Thanks so much for the purchase from us of the Curt Discovery Trailer Brake Controller # C84VV for your 2014 Cadillac Escalade, and I'm sorry to hear of this issue you are having. This controller, which you'd use with Wiring Adapter for Curt Trailer Brake Controllers # C51515 assuming the Escalade had a factory 7-way already, should not have anything to do with the vehicle starting or not, which means there was a mistake somewhere along the way with the wiring process. I have added a link...

• Trailer Running Lights Fuse on 2010 Cadillac Escalade
• The "Trailer Park Lamps" fuse, which looks to be located in the #25 position inside the power distribution box under the hood, is the correct fuse to check/replace on your 2010 Cadillac Escalade. Running lights are often referred to as park lamps. If for some reason replacing this fuse doesn't resolve the issue please let me know and we can do some more troubleshooting. If this is the case then there's likely something going on with the trailer wiring.

• Constant Power on Blue and Red Trailer Brake Controller Wires on 2007 Cadillac Escalade
• There should not be power all the time on the red wire or on the blue wire on a brake controller. You should not have to connect the red brake controller wire to the brake switch. You should be connected to the tow package wiring under the dash, to the left of the emergency brake pedal. There is a bundle of wires held together with a white tag. There should be a light blue wire here that you would use but not at the brake switch. It is also possible that if you are connected to the tow...

• 2011 Escalade ESV Electric Trailer Brake Controller Installation Troubleshooting
• On your 2011 Cadillac Escalade, the wiring present under the dash is most likely not connected correctly on your Prodigy P3 brake controller # 90195. There is a good chance that the red wire that connects to your brake light switch is getting the constant power signal. It should only receive power when the brake pedal is depressed. Use a circuit tester like # PTW2993 to test this connection. I've attached a video and an article to assist.
