04 F-150 alarm install?

I need some help with a few wires on an 04 F-150. I've never worked with an Autopage system before, and there is some sh*t I've never seen on here.  Autopage 520LCD

ORANGE / Red- main harness---Dome light relay power input.  Do I need this for the domelight or will the ORANGE / black below suffice??

ORANGE / Black- main harness--Dome light relay output.  Pretty sure this will go to source for domelight supervision, wehich is BLACK/ blue on truck.

Orange --main harness----(-) 500mA Grounded output when armed

Also, I have factory keyless entry. Am I correct in going to the negative door sense switching wire????(Green)

I have a sorta decent wiring diagram, and know where to pick most wires from, but if anyone has any suggestions, I am very open.

I hate to sound stupid, but this is the first alarm I've done in 2-3 years, and this brand is new to me.

OK, thanks.  Anyone have an idea on the Orange, or a positive idea on the door sensing????

Vehicles with keyless entry, the door trigger wires are found at the BCM, green plug. The LF door trigger is BLACK / YELLOW in pin 4. The RF door trigger is BLACK/ pink in pin 5. The LR door trigger is BLACK/ lt. blue in pin 12. The RR door trigger is BLACK/ white in pin 13. Use all wires and diode isolate each.

Thanks for all the help fellas, I got her done a little while ago.  Just did it the way I did the 94 and 99 f150's.  Just had to stop and think and get rid of a few distractions that were hanging around.
