Look right above and to the left of the brake pedal. There's a rubber grommet that you can push out and you can run the power wire through that hole.

Ensure that your doors are unlocked before you press the trunk-release button inside the cabin of the vehicle. The trunk does not seem to release (safety feature?) when the doors are locked. (Sorry, seen alot of people run into this problem.)

If you use a certain procedure (described further down), you can gain access to Diagnostic Trouble Codes (DTCs) and many other digital readouts from the trip computer display built into the Cougar's gauge cluster. Items that are displayed include, but are not limited to: RPM, MPH, Battery Voltage, Engine Coolant Temp, DTCs, etc.

1. Hold Down "Units" & "Reset" buttons on the trip computer while the car is off.
2. Turn the car on ... The gauges will reset (pet out) and then return to normal.
3. Release the "Reset" button, THEN the "Units" button ... in that order or it may not work.
4. Push "Select" to go through various Diagnostic Modes, press "Units" to switch between Standard and Metric measuring units, and press "Reset" to return to normal mode (gauge needles will peg out again).
