DO NOT USE A TEST LIGHT
Although many times it is harmless to use a test light, in only takes one poke to destroy a five thousand dollar body controller.
The easiest way is to start is by removing the Upper vents on the dash. Use a pick tool or panel tool. Be very careful it is easy to damage a nice dashboard. Take out the ashtray by removing the trim around it and take out the two bolts holding it in. Remove the screws that hold in the radio and temp controls. Unplug and remove.
The kit for the Lincoln LS is a rare one, but does exist. A kit may be fabricated out of ABS plastic but takes much custom work. Remove the metal sleeve from the aftermarket radio with enclosed keys. Either assemble the dash kit according to the dash kit instructions or make sure for good custom fit. Insert the metal ring into the dash kit assembly and bend back the appropriate metal tabs.
Connect the 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.
There may be an amplifier in some sound systems, but the majority are connected directly. Make sure you test this with a 1.5volt AA battery. You will not get a popping sound but a light click. After touching a battery to the appropriate terminal, touch the speaker wires together you will get another click. Another test for an amplifier is to connect only the power harness to the radio. Everything but the subwoofer will work. Check white and white/black, grey and grey/black and so on. IF the speaker makes a clicking noise, continue to connect the wires. If nothing happens, connect the blue/white wire to constant power and try test again. If they work after this is connected you have the amplified system.
If the system is amplified you may either connect to the amplifier with the RCA output on the radio, which can cause a popping when the stereo channels are changed, or install a premium sound interface unit with adjustable output. Connect the input to the aftermarket radio, and the output to the interface harness that plugs into the vehicle and adjust the resistors until there is no popping between source changes or radio station changes. Make sure to study instructions on unit before install. Make sure the blue with white wire is connected from the factory interface plugs to the new stereo. See below for details on amplifier interfacing.
To interface into the subwoofer, you can either do the RCA connection or the premium sound interface as above. To connect via RCA’s, connect RCA’s male connections as speaker outputs. Connect the negative or inner prong of the RCA to the corresponding white/black or gray w/black. And do the same for the outer ring or positive side and the wire associated with it, to the white or gray. Test for subwoofer with the AA battery and both blue w/white wires powered up in the square eight pin plug. You must have a radio with a subwoofer preout that is separate and adjustable. You can also interface into the subwoofer by using a premium sound interface. You will have to connect it either to the front or rear channels. Connect the input of the interface to the output of the aftermarket radio. Connect the output of the premium sound interface to the input of the subwoofer harness. You will only need one or two channels. Match the color of the wires together for the channels. Use this same procedure for a four channel interior speaker interface. If you find that you have a four channel amp running the interior speakers, these processes will work the same. You will just have two more channels to connect.
Plug in the harness to the aftermarket radio along with the antenna adapter and the dash harness and clip radio in to the metal sleeve. Install the radio into the opening and reinstall the dash.
