As a new owner of a terios 2 of 2007 is wished to upgrade the radio system with a set rear speakers (not installed before). After removing the door pannel and some other plastic molded parts. I could not find the speaker cables. After checking the connectors on the back of the radio i found the wiringcolours for the rear speakers. As they are incorporated in the main wiring harnass, is asume the can be picked up somewhere to connect the rearspeakers to the radio.
has anyone a solution or idea how to connect and at what place that has to be done?
