Thread: How to add factory nav to an 05-08 with HUD

This harness is great for adding the Vehicle Speed Sensor (VSS)! Just cut the box off and patch reconnect the wires as pass through. Then tap your wire from your VSS to the yellow wire which is the D wire according to the attached diagram. Then it is an extension of your factory harness that you can tap.
