Expert Answers about Custom Fit Vehicle Wiring


  • Flat Towing Wiring Kit for a 2018 Jeep JL Wrangler Unlimited
  • The Tekonsha T-One # 118786 that you referenced is for activating the light functions on a trailer when towing with your 2018 Jeep JL Wrangler Unlimited. It sounds like you are needing some wiring to flat tow your Jeep and for that you need some different parts. If you use the Hy-Power Diode Wiring Kit # RM-152 along with the Hopkins Mounting Bracket # HM48605 and the Pollak Heavy-Duty, 4-Pole, Round Pin Socket # PK11410 then you will essentially have the Flexo-Coil Wiring Kit # RM-15267...

  • Recommended Fifth Wheel Wiring Connection for 2017 Ford F-350 Super Duty
  • I spoke with a representative of Bargman, who told me that while # 50-97-410-010 will work with your 2017 Ford F-350 with the fifth wheel prep, there have been very, very rare occasions where it can read a trailer is connected when it is not. To avoid that issue, it is recommended that you use Bargman # 54701-007-010 for fifth wheel wiring with your '17 F-350. I've included a link to a video review of this product for you to take a look at.

  • For your 2017 Mazda CX-5 we have two trailer wiring harnesses available. The Curt part # C56377 and the Tekonsha part # 118746 which you mentioned. In general the Tekonsha kits are more reliable and less likely to short out.

  • Installation Process for 4-Pole Trailer Wiring Harnesses C56268 and 118652 on 2016 Lexus NX 200t
  • For the 2016 Lexus NX 200t F-Sport both of the aftermarket 4-pole wiring harness kits we offer, Curt # C56268 and Tekonsha # 118652, use a separate 12V power wire that will be run to the battery and connect through an included fuse holder. This separate power connection delivers the actual current to operate trailer lights, bypassing the vehicles internal wiring. This isolates the car's wiring from any potential damage from short-circuits on the trailer. Apart from this one power wire...

  • Best Trailer Wiring Harness for 2019 Toyota RAV4 Hybrid

  • Adding a 7-Way Connector and Brake Controller to a 2018 Ford F-150 with Factory 4-Way
  • I will be happy to get your 2018 Ford F-150 set up with a 7-Way trailer connector and a brake controller. The method for doing so that requires the fewest parts is to hardwire in the brake controller/7-Way. Since your truck already has a factory 4-Way connector you will just need # ETBC7 to add a 7-Way, retain the 4-Way, and have the parts needed to install a brake controller as well as run a 12 volt hot lead. If you do not already have a brake controller picked out I recommend the...

  • Recommended Wiring Kit for Towing with a 2017 Toyota RAV4
  • Out of the Curt # C56350, Tekonsha T-One # 118578, and Hopkins # HM11141820 wiring harness kits for your 2017 Toyota RAV4 Hybrid I highly recommend going with the T-One option. The reason being that we have found the Tekonsha electronic equipment to last longer and work better than many other brands. The installation is fairly simple and only requires you to plug in the T adapters behind the tail lights, grounding a wire, and then run a hot lead up to the battery. I have attached a...

  • Difference between Item # C56382 and Item # 118753 for a 2018 Honda Odyssey
  • The difference between the Curt # C56382 and the Tekonsha T-One # 118753 for your 2018 Honda Odyssey is that the Curt is for if the fuse locations actually have pins in them. The Tekonsha option is for if the fuse locations are lacking the pins to activate the tow wiring. The Tekonsha basically bypasses everything and pulls power straight from the battery via the black wire (which runs to your battery) while the Curt utilizes factory wiring on your vehicle.

  • Difference Between Wiring Harnesses for 2019 Mazda CX-5
  • Between the two wiring harnesses that fit your 2019 Mazda CX-5, Tekonsha # 118746 and Curt # C56377, I recommend the Tekonsha. It has a higher maximum amperage than the Curt. Another reason I recommend the Tekonsha is simply because we've always had better success with their reliability. I also prefer how the Tekonsha's converter box actually uses a screw to anchor it in place where the Curt's is just doublesided tape.

  • Installing a 7-way Trailer Connector on a 2018 Subaru Outback
  • We do have what you need to add a 7-way trailer connector to your 2018 Subaru Outback Wagon but there isn't a specific custom harness that fits. If right now the Outback has no trailer wiring at all the easiest way to add a 7-way is to start with a plug and play 4-way and then convert it. I recommend using the Tekonsha, part # 118467, for the 4-way. It plugs in to a connector that's either behind a trim panel in the rear cargo area on the driver's side or in the spare tire compartment....

  • How Does 7-Way and Brake Controller Install in 1973 Ford F-350
  • For a truck as old as yours it would be pretty hard to find a wiring diagram for installing the 7-way part # 20023 but I can help you figure it out using a circuit tester like the part # PTW2993. Basically you are going to need to test all of the wires of your taillights to determine their function and then wire to the 7-way using the included diagram. Now hardwiring in a brake controller will be a similar process but you'll only have to test the wires at the brake switch till you find...

Look at the picture I've attached. If it looks like this will plug into the connector you found then that's what it is. It shouldn't be a connector for a brake controller because your 2018 Toyota Highlander doesn't have a custom adapter to install a controller. If this is what you need then I recommend...

  • What are Differences Between Curt and Tekonsha Harnesses?
  • There are a couple of differences between the wiring harnesses for your 2016 Ram ProMaster. The biggest difference is the technology used.

  • Is Curt T-Connector Wiring Harness Safe to Install on 2019 Volkswagen Tiguan
  • If you are concerned with keeping the OEM wiring safe on your 2019 Volkswagen Tiguan then the Curt T-Connector # C56403 that you are looking at is actually the perfect solution! Yes it does tee in with the tail lights on your Tiguan but those basically just act as triggers. Since this wiring harness draws power directly from the battery on your VW and it uses an integrated module (the black box) so if anything were to become damaged from your trailer the ModuLite would stop it. The only...

  • Wiring Harness Recommendation for 2019 Nissan Pathfinder Without Tow Package

This harness will require the installation of a couple relays (as you can see in the accompanying photo) but remains...

  • Wiring Harness for 2016 Ford F-150 Without Tow Package

If the connector is round and looks like it will match up with picture # 1 that I've attached then you can use # 74682 and plug it right in to give you both a 7-way and 4-way trailer connector. If you find a connector that is more rectangular like in picture # 2 then you can use # C56110 which will give you a 4-way connector. If this is the...

The plug may be taped to an existing wiring harness. If you have this plug then you can use part # C55384 to add a 4-way trailer connector or part # C55774 to add a 4 and 7-way trailer connector.
