Debbie133 Posted April 21, 2018 Share Posted April 21, 2018 Hi. I am looking at the Toyota Highlander and the dealer cannot seem to provide advise about what the tow package includes. I do know it only has a 4 pin connector and I need a 7 pin one. He said the 4 pin would be fine --- but of course, then I could not use things like, uh BRAKES. Yikes! I have seen people write on other forums about adding a 7 pin connector, wiring and discussing adaptations way beyond my capacity. Can anyone tell me exactly what the tow package includes; if they have made adaptations and who did the work --- e.g., the dealer or someone else; if someone else did it effect the warranty? Any what was your experience towing. I am looking to tow and 16 or 17 foot Casita travel trailer that has a dry weight of about 2300 pounds. Would love to hear others experiences. Thanks.

Toyota Owners Club Posted April 23, 2018 Share Posted April 23, 2018 Hi Debbie133...welcome to the Forums I would probably entrust the installation to an authorised installer as the system would need to be wired correctly to work with the CanBus system. If it is wired incorrectly for the vehicle then it can interfere with the onboard electronics with disastrous effect. Quote Link to comment Share on other sites More sharing options...
Paty Watkins Posted September 21, 2018 Share Posted September 21, 2018 Hi Debbie133. I am just now going through the exact same ordeal. I bought a Scamp13 with brakes and cannot tow it with my 2016 Highlander because it has the 4pin flat connector. Were you able to solve your issue? Can you advise?

FJR Posted December 16, 2019 Share Posted December 16, 2019 When I ordered my 2018 Highlander Limited from my Canadian dealer, I requested and got both the 7 pin and a 4 pin connector along with a brake controller. The attached photo shows a 7 pin to 4 pin adapter stuck out from beneath the "7 Way" flap. That was not included. I only added it to test something. To use the 4 pin connector you must unplug the left 4 pin male, thereby making the 7 pin dead. Silly set up. I bought an aftermarket 7/5 pin replacement to neaten up the installation. See photo on right below. Quote Link to comment Share on other sites More sharing options...
