Sorry for the disclaimer- since I am new to the site I don't want people to shout at me to use the search function! I read many threads on trailer wiring harnesses, BUT... do I use the connectors underneath the car (that the factory service wiring manual refers to for trailer wiring) or the connectors in the back right panel near the passenger side tailight? The prior threads refer to both, in some threads interchangeably! I DO have the connectors underneath (97 LX450) and would prefer to use those since they are already outside the car and right there by the hitch (aftermarket, just installed it). I am picking up the Hoppy harness # 43405 tomorrow morning, at least one user said he used the Drawtite 18357 and connected it underneath the car. Is the Hoppy only good for connecting inside the vehicle inside that panel? I do not have the factory black box in there. Thanks! Edit: To help with other people's searches, the drawtite: http://www.etrailer.com/Merchant2/m...e_Code=E&Product_Code=18357&Category_Code=VWH The Hoppy I got at a local advance auto, they order them in but have them the next morning.
