Modulite Protector with Integrated Circuit & Overload Protection

- 119177

After another store botched my SUV wiring installation leading to a short circuit and a need to rewire, I found this item for a great price. I wired it myself. It was simple and has worked perfectly with my LED lights and new trailer wiring. Very happy.

Still working perfectly, with zero issues to date.

  • How To Convert a Euro 13-Pin to a US 5-Way Trailer Connector
    If the trailer has reverse lights then you will want to use the Modulite Protector 5-Way Flat part # 119177 instead of the Upgraded Tail Light Converter part # 119130 on your 2011 Volkswagen Jetta. Then in order to make an adapter that attaches the Euro 13-Pin connector on your trailer to the US 5-Way connector on your vehicle you will need the following: Hopkins Wiring Harness with 5-Pole part # HM37918 Curt 2-To-3-Wire Tail Light Converter part # C56196 Vehicle Side Euro 13-Pin Connector...

  • Recommendation to Install 5-Way Connector on 2008 Honda Ridgeline
    The Tekonsha Modulite Protector 5-Way Flat # 119177 referenced in your question is a universal harness that can be installed on your 2008 Honda Ridgeline. This hardwire kit will require you to splice in all of the wires to the tail light wires on your Honda Ridgeline to give you the needed 5-Way to connect with your boat trailer. With this in mind, an easier option will be to simply install the Tekonsha T-One Vehicle Wiring Harness # 118400. This custom-fit, 4-Way harness will connect...

  • Availability of 5-Pin Flat Connector That Retains Separate Stop and Turn Signals for 2016 VW Golf
    Since pretty much every trailer has the stop signal integrated with the left and right turn signals it has just become the standard wiring configuration and that is why it can be difficult to find something. Despite this, we actually do have the solution you are looking for. Tekonsha has their Modulite Protector 5-Way Flat w/ Integrated Circuit and Overload Protection # 119177 which will work in the same manner as the wiring kits that you see are a fit for your 2016 Volkswagen Golf....

  • 5-Way Trailer Wiring Harness Recommendation for a 2008 BMW X5
    Since all of the trailer wiring options we have for your 2008 BMW X5 are hardwire options the best solution will be to use the # 119177 which is also a hardwire option but it comes with a 5-way that you can wire the reverse light circuit to. This way you wouldn't have to deal with any adapters.

    The Tekonsha Modulite Protector 5-Way Flat # 119177 is what you are going to need to install a 5-way in your 2017 Nissan Armada. This will require you to splice into your vehicle's wiring for all the circuit including the reverse light. Since the reverse light is in the rear hatch of your vehicle you'll have to find the wiring harness up near the hatch hinge that has all of the taillight wiring and test all of the wiring there till you find the circuit that has power only when the vehicle...

  • Will Trailer Wiring Harness # 119177 Fit a 2007 Dodge Ram 2500
    You could use trailer wiring harness # 119177KIT if you needed a 5-Way flat trailer connector. However the 5th function is not for trailer brakes it is made for use with a trailer that has an electric reverse lock out on a surge coupler. When the vehicle is put in reverse it sends power to the solenoid which does not allow brake fluid to go back to the trailer brakes so the trailer can back up without the brakes engaging. If your truck did not come with any kind of trailer wiring...

  • Can a 5-Way Hardwire Trailer Wiring Harness be Installed on a 2004 BMW X5
    Yes, you can use a 5-Way hardwire trailer wiring harness on your 2004 BMW X5 but I recommend # 119177KIT since it comes with the additional wiring and other parts you will need to complete the installation.

  • How to Add 5-Way Wiring Harness to a 2012 Ford Edge
    We do have some options for you to add a 5-Way wiring connector on your 2012 Ford Edge, but the available wiring kits that tee in behind the tail lights don't come with 5-Way connectors. Your options to adding a 5-Way include using a wiring kit like the T-One # 118515 and then cutting off the 4-Way and splicing in a 5-Way like the Hopkins # HM37908, OR you can just install a 5-Way harness that splices in completely like the Tekonsha # 119177. Attached are some videos you can check...

    We have a couple different options that will work to give you the 5-way connector on your 2010 Ford Escape for your reverse LED lights or reverse lockout solenoid circuit. The easiest route may be to get the T-One Vehicle Wiring Harness, # 118551, and the 4-way to 5-way Adapter, # 20036. There is minimal splicing involved with this application.
