Question:

For the eco invisi-hitch 306-X7257… I have a 2015 STI. When adding wiring for a trailer to mate with the invisi-hitch, is it possible to wire the trailer to work with brake and turn signals WITHOUT removing the drivers side trunk liner? The liner I’m talking about is behind the amazing looking methanol mount i made hahaha. If the wiring behind that trim panel does need to be accessed, can it be accessed when the bumper cover is removed during the invisi-hitch install? Thank you

While that is a great looking mount you are going to have to get behind the trunk liner to access the connections for the Curt T-Connector Vehicle Wiring Harness # C56259. There is no way to access the tail light connections even with the rear bumper cover removed during the installation of the EcoHitch Invisi Trailer Hitch Receiver # 306-X7257. While having everything removed it will also allow you to run the 4-way wiring outside the trunk area so you can secure it near the receiver rather than having to run it out the tailgate when you need it. We do have the Bracket # C42CR if you wish to secure it near the bottom of your fascia.
