In this video you we walk you through the wires that are used when installing any aftermarket radio to your Acura TL. While this video is exclusive to an 2004-2006 TL we do carry the harness necessary for 2007-2008 Acura TLs. Here is a breakdown of the connectors. The 26 pin connector(gray) first shown in the video contains the most important amp turn on wire for your factory amplifier. This means if you do not hook up this wire to the remote signal coming from your aftermarket radio your factory amp will not turn on and you will have no sound. You can wiretap this wire and connect to your amp turn on from the aftermarket radio or you can use this harness.
If your Acura TL has navigation you will need to splice in a resistor of 68ohms in between the blue and red wires shown in the video. This will enable the touchscreen on the navigation models to work. Without this resistor your touchscreen will not function.
If you are planning to keep the factory subwoofer you will also need to wire tap or splice the white/green wire and blue/red wires shown in the video. These wires are the negative and positive wires of the subwoofer input that feeds the rear subwoofer in the vehicle.
Also note you will loose the center channel, factory navigation guidance and some HFL features when installing an aftermarket radio
