    Procedure

    Take your ford keys insert them into the radio on each side slowly at the very first click, pull apart and out. The radio is now removed from your Lincoln Town Car.

    Remove the metal sleeve that came with the aftermarket radio with enclosed keys. Slide trim ring along this sleeve and insert into the dash. Bend according metal tabs back to secure sleeve and trim ring.

    Take the amplifier bypass harness (the harness with a plug on each end). Get into the trunk of your Lincoln Town Car and unplug the two largest connectors. Insert each into their respective slots in the amplifier bypass harness.

    Connect aftermarket radio harness and wiring harness wires verbatim. Connect the bare ends together. Black to black, red to red and so on. There may be some that are not used such as orange with black etc. Tape those connections off. Don't forget the blue wire or the power antenna will not go up.

    Plug in the harness to the aftermarket radio and the dash harness and antenna and clip in to the metal sleeve.

    Note: The square black plug may give you trouble. You may need to play with the pins and arrange them to fit the gray shielded harness. Best of luck.

    To keep JBL premium system in your Lincoln Town Car: If you have the JBL premium system and wish to keep the subwoofer just with a cd display you may use the factory amplifier system in your Lincoln Town Car. It will sound no different but will give you a new cd player. For these instructions see below

    Take your ford keys insert them into the radio on each side slowly at the very first click, pull apart and out. The radio is now removed from your Lincoln Town Car.

    Remove the metal sleeve that came with the aftermarket radio with enclosed keys. Slide trim ring along this sleeve and insert into the dash. Bend according metal tabs back to secure sleeve and trim ring.

    You must have a radio with two sets of rca preouts or an rca y splitter. Take the negative lead of one of the rcas (usually the inner lead) and connect it to the according negative speaker wire. Connecting the positive lead of the rca to the positive speaker wire. Continue with the other three speakers. When finished the black square plug will have rcas with male ends on them.

    When connecting the long grey plug make sure to connect blue with white wire to the blue with white wire. This is the wire that will power up the amplifier system of your Lincoln Town Car.

    Connect the rest of the wires verbatim and connect the antenna as described earlier and insert radio into the dash of your Lincoln Town Car until it clicks. Power up radio. You will hear intermittent clicks in between stations because of the higher voltage input. The only way to eliminate this is to use a premium sound interface and connect that to the speaker wires and adjust the attenuation of the unit for proper input signal. The latter is easier but the premium sound interface allows for more adjustability.



    Lincoln Town Car Speakers

    Front Speakers: Snap out the two door pull strap retaining screw covers. Remove the screws. Remove the two screws on the front and rear side of the door trim panel. (may be concealed in carpet) Using the trim pad reoving tool, pry the trim panel retaining clips from the door inner panel. (try lifting up on the door panel firmly first, it may come off easily) Remove the window regulator switch housing from the back of the front door trim panel. Lift up on the housing and disconnect all connectors from the switch housing. Disconnect the driver seat regulator control processor switch if equipped. Twist out the interior lamp wire assembly. Installation reverse of removal.

    Rear Speakers: Remove the cover over the rear speaker and the black pins that hold it in. (This is a shortcut that may break cover to speakers use your own discression) Another way is to Put a knee in the rear seat to dislodge the seat clips from the seat on each side. Remove the torx nuts that hold in the seatbelts. Remove the rear seat. Remove the package tray. Remove the speakers. Installation is reverse of removal.

    This is the best way to change the factory unit in your Lincoln Town Car to an aftermarket one. It is reversible and clean install.

    Note: If a radio with a higher power amplifier is purchased, run the 10ga amp wire to the batter and do not connect constant power to the harness behind the display unit in the dash. It may cause wire damage.
