key chime sounds if the little tab is grounded where the key contacts it. The theft light is supposed to blink when the system is armed to let you know it is armed. That's normal.

NOTE: The generic electronic module/central timer module (GEM/CTM) is connected to the ISO link and is diagnosed through the data link connector (DLC) with New Generation STAR (NGS) Tester.
There are five warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat belt warning (chime and lamp), and message center.


Audible Warnings Warning Condition Lamp Duration Audible Duration Audible Output Safety Belt 60 Seconds 6 Seconds Chime, 60/Min. 740 Hz Key In Ignition — Continuous Chime, 120/Min. 740 Hz Headlamps On — Continuous Chime, 240/Min. 740 Hz Door Ajar Continuous 1 Second Single Tone, 1000 Hz Message Center (Tone Request) — 1 Second Single Tone, 1000 Hz
When the is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
The will turn on for 60 seconds or until the driver safety belt is fastened. Both the chime and the lamp turn on at the same time.
If the safety belt is buckled before the ignition switch is turned to RUN or START, from OFF or ACC, neither the chime nor lamp will be activated.
Anytime the is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed or the safety belt is buckled.
When at least one door is ajar and the key is in the RUN position, the door ajar cluster lamp is activated and remains on until all doors are closed. A warning tone will sound once any time the key is in the ignition switch and any door is open.
The key-in-ignition warning will sound when the driver side is opened with the key in the and the in OFF or ACC. It will continue to sound until the key is removed, the is closed, or the is in RUN or START.
The headlamp-on reminder chime will be activated if the headlamps or parking lamps are on, the key is not in the ignition switch, and the driver door is opened.
A single tone will be provided each time a ground signal is received from the message center. A one-second tone will sound for warning indications from the message center. A 100 milli-second tone will sound for each message center button depressed.

THE SOLENOID NEEDS REPLACED

those nuts are 5/16ths.

fuses # 10 and 21 , 10 is a 7.5 amp fuse , and 21 is a 15 amp fuse. They are in the fuse box inside the vehicle .

What throws everybody is that the pcv valve does not insert into the valve cover as it does most cars. This one on the 1999 explorer is located directly behind or in back of the engine on the top of the manifold. You can spot this easier if you take off the covering(four screws) on manifold then you will see two hoses that connect to a plastic pcv valve (that's what threw me). this should help.

Condenser coil should unbolt from the radiator

If your wires somehow got disconnected or burnt go to a junk yard and cut out the connector with as much wire as you can get then match them up color to color or buy the chiltons book but it might not have that so the junkyard is the best solution
