  • Troubleshooting Curt Round Spring Back Stuck In Weight Distribution Head
  • To remove the round bars on your Curt Weight Distribution Hitch you will need to slightly lift up on the spring bar to remove the clip included in the Curt retainer Clips # 17109 and then pull out on the retaining pin on the hitch head. Now if the spring bars were not greased regularly it is possible they may have a bit of rust and corrosion holding them in and you may need to have another person pull down on the bar while you are pulling out on the retaining pin. When reinstalling the...

  • Er or E1 Error Message on Trailer Brake Controller
  • If you have the Activator brake controller 5500 then the error you are seeing should be Er (though on the display it might look like E1). This indicates an internal problem with the controller and it will likely need to be replaced. It would have to be sent back to Draw-Tite to determine what is even causing that particular message. When a brake controller shows that a trailer is connected even though there is no trailer connected it is almost always caused by a short. And the short is...

  • No Power On Brake Light Circuit When Installing a Brake Controller
  • The brake signal should be fused. Check the vehicle owners manual for the fuse locations for the stop light switch or CHMSL (center high mount stop lamp). If either is blown there would be no power at the plug you found. If you have a Chevy or GMC truck/SUV then it is also possible that there needs to be some connections made under the hood to make everything fully functional. I would need to know the year, make, and model of the vehicle to know if there are any peculiarities with your...

  • Troubleshooting Running lights on 4-Way Connector Not Working
  • I recommend first checking the fuse box in your engine bay and checking your trailer park lamps fuse to ensure it is not blown or missing. If the fuse is there and working correctly I recommend unplugging the wiring harness from the back of your new dual 7-Way and 4-Way connector and verify that none of the contacts inside of the dual connector are damaged causing power to not be transferred through the plug. While there, ensure all wires are tight in the connector and do not have any...

  • Troubleshooting Hoppy Plug-n-Tow Harness with no Right Turn Signals on a 2006 Chevy Colorado
  • The best way to determine if the converter is damaged is to check the wires right at the box. Using a circuit tester, like part # PTW2993, probe the green wire just ahead of the box. If it does not have power, then the wiring may have come loose in the connectors or inside the taped wires. If it does have power, check the green wire on the other side of the converter. If this one does not have power, then the converter could be bad.

  • Door Locks on 2019 Chevrolet Colorado Do Not Work After Pop & Lock Install
  • I spoke to my contact at Pop & Lock about the Pop & Lock Custom Tailgate Lock part # PAL8140 for your 2019 Chevrolet Colorado and they seem to think you have the device tied into the wrong circuits. The correct circuits that you will need to use will be located at the back of the 27 pin plug coming from the PCM, under the driver dash. On this 27 pin plug there is a brown/yellow wire on the 4th pin that is used for the lock signal and then a gray wire on the 1st pin that is used for the...

  • Red Light Flashes on Primus IQ After Battery Was Replaced on a 2005 Chevrolet Colorado
  • The first step I would take is to reset the brake controller. To do this, you simply unplug the connector at the back of the brake controller for about 20 seconds and the reconnect the connector to the brake controller. I spoke with my contact at Tekonsha and he told me that this can happen when the vehicle batteries are replaced, especially if the brake controller is left connected in the vehicle while the battery is being replaced. If you reset the brake controller and continue to...

  • Hopkins Agility Brake Controller Will Not Turn Back On
  • If you Hopkins Agility Trailer Brake Controller # HM47294 has not powered back on, it will mean one of two things. The brake controller fuse on your 2019 Colorado blew and will need to be replaced, or the controller shorted and it will need to be replaced. To start with, you will need to check the fuse in position F27 in the fuse box located in the engine compartment, picture included. This will be the one that handles the trailer brake controller. If this has indeed blown, it will need...

  • Why Isn't My Brake Controller Lighting Up When In Use
  • If you are having trouble with your Redarc controller # RED24FR you need to first check the fuse that powers the brake controller. If you check the owner's manual it will let you know where the fuse is located at. You can also make sure that all of the pins on the receiving connector are all connecting with the controller itself. Sometimes the pins in the harness can get damaged or bent to the point where you would need to get a replacement adapter another option is to check that all the...

  • Recommend Weight Dist System with Sway Control For Trailer with GVWR of 4,900 lbs
  • The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. Based on that the Reese Steadi-Flex...

  • Troubleshooting Pacer 3rd Brake Light Module Installation on 7-way Trailer Plug
  • In most cases when this occurs, it's down to the wiring being connected to the wrong spots on the 7 way trailer plug. You'll want to be sure you're using the 3 o'clock and 9 o'clock pins when looking at the back of the plug. I've attached a wiring diagram that shows this in better detail that I would ask you to confirm is how you have this wired. If this is exactly how you have it wired please let me know and I will be happy to look into this further.

  • Troubleshooting a Kat's Heaters Custom Fit Engine Block Heater # KH11484 Causes Outlet to Cut Out
  • If you have a Kat's Heaters Custom Fit Engine Block Heater # KH11484 that you referenced and it is causing the outlet of your vehicle to cut out then the problem is that the outlet is getting overdrawn either by the heater drawing too much amperage for the outlet to handle or because the heater has a short in the wiring of it and that's causing the outlet to short out. I would recommend you go over the wiring of the heater looking for any cuts or other obvious signs of a short as that...

  • Troubleshooting Trailer Connector And Wiring On 2012 Chevrolet Colorado
  • When a 7-way connector was installed on your Colorado, a converter should have been included because the vehicle has separate lighting meaning the brake signal and turn signals are sent along separate wires. It sounds like the wiring kit was not installed correctly. For your 2012 Colorado, I recommend a wiring harness like part # 118301. This harness plugs into the truck wiring under the truck bed on the driver side. I recommend using a circuit tester like part # PTW2993 and test the...

  • Troubleshooting Wiring Harness Failure for 2004 Chevrolet Coloroado
  • Checking for shorts is a great first step in troubleshooting your lighting issues. As you mentioned, a regular wiring harness converter box has a max amperage of 2.1 amps per circuit for stop and turn lights, and a max amperage of 5 amps per circuit for the tail lights. The Tail Light Isolating Diodes # 48955 you mentioned have a max amperage of 3 amps. There are several other things to check that might be causing your problems. Checking these additional components will ensure that you...

  • Troubleshooting Curt 55510 Trailer Wiring Harness with Low Voltage
  • Your problem could be the converter box. Test the wires on the harness before the box and see if you get the same voltage. If you do then the box isn't the issue and it's somewhere in the wiring before that. In this case you'll need to keep tracing the wires towards the front of the truck to find the problem. If the voltage on the # C55510 harness before the converter box is normal and still low at the connector then the converter is bad.

  • Troubleshooting Lifting Corner of Extang Trifecta Tonneau Cover on 2018 Chevy Colorado
  • I reached out to my contact at Extang and the front corner raising is a sign of the clamps not being installed correctly. He said you will want to remove the front clamp by removing the knob and then rotating the body up until the thread shows only about a 1/4 inch. Then reinstall the knob and secure the cover. He said you will want to do this on both sides of the bed. That will tighten the tension on the cover in the front and will also give you a better seal. No additional clamps...

  • Troubleshooting Vehicle Wiring Harness # 41165 Installation on a 2006 Chevrolet Colorado
  • To isolate where the problem is occurring, I recommend testing the 4-Way plug on the # 41165 wiring harness with a circuit tester, without the trailer connected. Have someone assist you by engaging the tail lights, pressing the brake pedal, and flipping on the turn signals as you test each corresponding port on the plug. You should only see a flashing current on the yellow (left turn) and green (right turn) ports when the turn signals are activated. If the functions are reading correctly...

  • Troubleshooting No Running Lights on Trailer Wiring Install of 2007 Chevy Colorado
  • First thing you might try is disconnecting and plugging back in the connection point on the right hand side of the truck. That's the connector that connects to the running light circuit on that side of the truck wiring. Often times this issue gets cleared out by just doing this. If not, you can try taking a circuit tester like # PTW2993 and testing the brown wire leading into the box for voltage when the circuit is active and then check the brown wire that leads to the 4-way. If voltage...
