• Curt Brake Controller # C24VV on 2012 Honda Odyssey Showing OL Error Code
• The OL error code you mentioned indicates an short somewhere in the brake controller output circuit between the blue wire exiting the brake controller and the trailer connector. You can confirm this by severing the blue wire behind the brake controller, being sure to leave enough room to reconnect the wire. If this makes the OL code disappear, you have confirmed the short. If this is the case, you'll need to rewire the output circuit, using 10 gauge wire like part # 10-1-1. Chances are,...

• Troubleshooting Trailer Brake Controller Not Detecting That Trailer Is Connected
• I would be happy to help, but there are a few troubleshooting steps you can try before diving into replacing the 7-way connector on your trailer. First using a circuit tester like # PTW2993 test the 5 o'clock pin on the # C57674 while a friend activates the manual override lever on your trailer brake controller. If you are not getting power, then there is no signal coming from the trailer brake controller to the 7-way connector. If this is the case, then you will want to trace the wire...

• Troubleshooting Trailer Lights not Working After Harness Install
• There are a number of steps for you to take to figure out exactly why the lights on your trailer are not working. You did not specify the harness you used, but for a 2007 Honda Odyssey, there are three fits, the T-One # 118438, Curt # C56161, and Hopkins # HM11143115. To start, we'll isolate the problem to either the trailer or vehicle. You can do this by using a circuit tester such as # PTW2993 to check the functions of the 4-way plug while somebody else engages them (brake, turn signal,...

• Troubleshooting Trailer Wiring Harness that Uses Converter Boxes
• What you will want to do is test the wires going into the box of the converter box for voltage with a circuit tester like the # PTW2993 to see if there is voltage going into the box when the taillight functions of your vehicle are applied, and then test the output side of the box to see if the current is making it through the converter. If not then the problem is that the converter box has shorted itself out and would need to be replaced. Before you replace it you will want to inspect...

• Trailer Running Lights Not Working When Connected to 2012 Honda Odyssey with Curt Wiring Harness
• The first and easiest thing to check is the ground connection for Curt wiring harness # C56378. A weak ground could be causing the problem. The ground should be attached to a clean and corrosion free bare metal surface on your 2012 Honda Odyssey. You may need to sand away any paint or coating to get to bare metal. If that does not solve the problem then there are a few other things you can check. I have included a link to our help article on troubleshooting 4/5-Way connectors. This is...

• Troubleshooting 4-Pole Harness 118521 Installation in 2016 Honda Odyssey
• Thank you for your purchase from etrailer of the # ETBC7 brake controller installation kit. This kit includes parts to install and wire the trailer brake controller of your choice, such as the Prodigy P3 # 90195. It does include a 7-way vehicle socket that plugs in to your existing 4-pole harness. I did not find any purchase history for a 4-pole harness, but Tekonsha part # 118521 is a correct fit. You are correct that your next troubleshooting check will indeed be on the 4-pole set-up....

• Troubleshooting Leak Where Quick Connect Attaches to OEM Hose on 2011 Honda Odyssey
• I definitely understand not wanting to take apart your vehicle, so I hope the hose and clamp are the issue. The Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13503. Based on the fact that you have a mushy end, it sounds like the hose is deteriorating and needs to either be cut back to a tighter fit location or that hose should be replaced. You most likely just need to trim back that hose and reinstall the quick connect with a hose clamp. If you need new clamps, I recommend...

• Running Light Circuit on TowReady T-One Vehicle Wiring Harness # 118521 Shuts Down
• Thank you for your purchase from etrailer. The problem you describe of just the running light circuit on your T-One Wiring Harness # 118521 going dead after a short period of use could have two causes. Either the harness is damaged internally or your trailer's running lights are drawing too much current (in excess of the unit's 7.5-amp capacity for this circuit). This 7.5-amp rating is fairly high, but still it could be the reason. Since the unit appears to reset itself once you turn...

• Troubleshooting Trailer Wiring Circuit Tester Not Able to Show Brake Controller Connection
• Brake controllers don't always show a trailer connection when connected to a circuit tester because they are looking for a larger amperage draw on the circuit from brake magnets to know a trailer is connected. Circuit testers often use a small LED indicator light which isn't enough of a draw for a controller to think a trailer is connected. Sounds like everything is connected and working well but you'll have to find a trailer to get a real test.

• Curt Trailer Brake Controller Does Not Apply Trailer Brakes when Connected to 2005 Honda Odyssey
• The most likely culprit is going to be either a dirty or corroded trailer connector or brake magnet wiring. This can cause a short or a weak connection. First, disconnect the trailer and examine the vehicle side connector. Clean off any dirt or corrosion on the pins. Also check the back of the connector where the wires attach because corrosion can build up there as well. Once you have done that use a circuit tester like # PTW2979 if needed to test the brake output pin (5:00 position)...

• Trailer LED Tail Lights Light Up Dim When Connected to Vehicle with Curt Trailer Wiring Harness
• Curt trailer wiring harnesses like # C56378 sometimes have the exact issue that you are describing. The issue is that there is some bleed over power from the powered converter that can light up LED lights ever so slightly. This is usually not an issue because at night you would have the running lights on any way and during the day it should not be all that visible. The reason that it happens with LED lights and not incandescent lights is that the LED lights draw much less power to light...

• Curt Trailer Wiring Harness for 2006 Honda Odyssey has Constant Power
• Are the lights on the trailer actually lighting up or just the circuit tester? If the trailer has LED lights then it is more likely that Curt harness # C56161 will cause them to dimly light up. Curt trailer wiring harnesses that are powered like this one sometimes have this issue. The converter is working properly but for some reason a little power bleeds through causing this exact issue. The Tow Ready harness # 118438 does not have a history of this issue and would be the preferred wiring...

• Troubleshooting Damaged Trailer Wiring That is Causing Vehicle Fuses to Blow in Honda Odyssey
• Damaged trailer wiring, such as worn insulation that can cause a short, should be repaired before you replace your vehicles fuses or chances are that you will be doing that regularly. In some cases a short on a trailer can damage a tail light converter, such as the Curt T-Connector Vehicle Wiring Harness # C56161 that you referenced. Check your trailer wiring all the way from the connector to the light fixtures themselves. Inspect the wires for cracked or worn insulation, especially in...

• Trailer Stop and Turn Signals Stop Working On 2012 Honda Odyssey
• It sounds like the converter is defective on the wiring harness. Unfortunately, this means the entire wiring harness will need to be replaced. The converters can fail over time on their own but the most common failure is caused by the converter not being secured enough and the wires inside coming loose from the circuit board. For replacement, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118521 which we have found to be more reliable than other manufactur...

• 2013 Honda Odyssey Traction Light On with Tekonsha Voyager 39510 Brake Controller Installed
• Since your Voyager brake controller # 39510 is operating correctly it is likely that the dashboard error messages you're seeing could be due to an incorrect wire used for the input signal. The # ETBC7 kit you purchased includes a circuit tester that allows you to test each wire at the pedal to find the ONE wire that goes hot ONLY when the pedal is pressed and at no other time. Auto makers can change wire colors without notice so testing is really the only truly good way to find the correct...

• Converting 6-Way Square to 4-Way Flat on a Honda Odyssey
• There are a number of wiring situations for the 6-Way square connector. Your trailer may have a battery, trailer brakes and/or backup lights, along with the taillights, left stop and turn light, right stop and turn light and ground wire. You said your trailer has a battery. If the battery circuit was somehow connected to the vehicle lighting circuits, you may have damaged the converter attached to the trailer wiring harness that switches the Odyssey 3 wire system down to the trailers two...

• Troubleshooting Trailer Turn Signals that Both Blink When One is Applied
• Sounds like the left and right stop/turn circuits are shorting out to each other somewhere. Typically this is a corrosion issue or cut or exposed wire. You will want to start at the connector looking for corrosion or bent pins and work your way to the wiring looking for cut or exposed wire making your way back to the light assemblies. I attached a help article on troubleshooting trailer wiring for you to check out as well.

• Tow Ready # 118521 T-One Connector w/ Malfunctioning Running Light Circuit on 2013 Honda Odyssey
• The first thing you'll want to do is test the converter. You'll need a circuit tester like part # PTW2993. Turn the vehicle running lights on and test the brown wire entering the converter. Then, test the brown wire on the 4-pole, to see if there's power leaving the converter. If there's power going in, but not coming out, the converter is faulty, and should be replaced. Also, go ahead and duplicate the test you did on the connector with an incandescent tester. The LED testers aren't very...

• Troubleshooting The Installation Of Draw-Tite # 75270 On 2008 Honda Odyssey
• This is not a normal fit for the Draw-Tite # 75270 on your 2008 Honda Odyssey. I reached out to my contact at the manufacturer and they said that is a big hitch and it can get tweaked side to side. If it is that side to side that isn't lining up, it sounds like it was tweaked. It should measure 53-1/8 inch center to center on those slots from side to side. If it was way out, it would most likely be a drop during shipping but is possibly a mis-drill, but it sounds really close. To...
