Note: using an optional snap on wire harness adapter will simplify the wiring. Most snap on
wire harness adapters have already converted and color coded the wires from the auto
makers in dash wire harness to match typical aftermarket radio wire colors.
** The wire colors listed in the chart above are typical for these vehicles during these years
but may not be the exact colors for this vehicle. This is another reason to use a snap on
wire harness adapter. **
