Kaiden_grennan Posted October 5, 2023 Share Posted October 5, 2023 Hello I have a 2004 toyota highlander and im trying to hookup and trailer harness and im getting absolutely no response to the big white plug u snap the harness up too. And when I buy a harness thay plugs into my tail lights I blow a fuse whenever I turn on my running lights? Any ideas of the issue? Quote Link to comment Share on other sites More sharing options...
Toyota Owners Club Posted October 6, 2023 Share Posted October 6, 2023 Certainly a wiring issue but one which would require further investigation to avoid damaging any electronic units As the vehicle is 2004 it shouldn't be loaded with CanBus systems so relatively straightforward wiring, in theory Quote Link to comment Share on other sites More sharing options...
