I purchased a GWH-406 wiring kit to install a Jensen VX7020 in a 2013 Silverado. The harness that I purchased does not have an orange (illumination) or green/black (reverse) wires on it. When I purchased this harness I thought I would not have to splice any wires. Did I order the wrong harness? If not could you help with where I connect these two wires>
