I am hammering away on this alarm and have a question
Alarm Matrix RS3
Truck 2000 Ford F250 Diesel
Questions:
What does the dome light supervision on the alarm do? Does it provide illuminated entry when the doors are unlocked via the alarm?
Next question, from one of the wiring diagrams the door trigger wire I used was a 12+ up under the dash (right where wiring diagram stated). It looks like this senses when the dome light comes on (watching multi-meter) now my question is if the dome light supervision does provide illuminated entry then do I tap into this same wire, via a relay, to make it all work?
Thanks for your time

The domelight supervision output will do three things:
1. When you unlock the car, the domelight will come on (for up to 30 seconds). When you get in the car and switch the key on, the light will go out.
2. When you arrive at your destination and shut the car off, the domelight will come on so you can find your belongings before you step out.
3. When the alarm is violated, the domelight will flash to attract attention.
To answer your next question, yes, you can use a relay to power up the domelight wire and all will be fine.
If you want to save the extra labor and expense of using a relay, you may be able to find one of the individual doorswitch wires....this wire would catch just one of the doors, not all of them. Usually, these wires are low-current negative, and you can directly connect the alarm's domelight output without a need for a relay.

Notes:
NOTE: Some models of this vehicle are equipted with PATS (Passive Anti Theft System). Use DEI module 555F to over-ride during remote start. *1 Power this wire if vehicle is equiped with only rear anti-lock brakes. Vehicles with all wheel anti-lock brakes do not have this wire. *2 Negative pulse, type 'B', on keyless entry models. Five wire, type 'C', on non-keyless models, mastered from the driver switch. *3 May also be found at trailer connector next to diagnostic connector under dash. *4 If equiped with autolamps. *5 The BLACK / YELLOW catches the drivers door and the BLACK/ pink catches the passengers door. Use both wires and diode isolate each. See direct fax document # 1076 for wiring information. The wires are found in there respective door harnesses. Both wires may also be found at the GEM module located above the fuse box. On models without a dome light delay use ORANGE / lt. green (-) at the light switch. *6 Arms when locked with the door open. To simulate, send a negative trigger to the lt. blue/white wire at the RAP module, located behind the light switch, while locking. *7 Tach wire : on the 4.2L it is a dk.blue/lt.green at the coil pack on top of the motor. Tach wire : On the 4.6L go to any of the 8 ignition coils and use the wire that is not RED / green. Tach wire : on the 5.4L it is a lt.GREEN / WHITE at the coil on the passenger side of the motor between the fuel injectors.

I will check on that, but I am pretty sure it is a negative from the alarm on this wire
