How to trigger running board lights and interior lights on '98 Expedition?
Hi everyone! I'm new to the forum. I own a '98 Expedition XLT. I would go ask this on the Expedition forum, but this forum seems to be more active, and based on threads I've read that came up as results on Google, you guys seems to have a much better grip in at least the wiring department 
So my truck came with a factory keyless entry/alarm. I just finished installing a Code-Alarm CA6552 which is keyless entry/alarm/remote start combo. None of the wiring that I did for the new system tapped into the factory alarm. I went directly to the door lock and unlock wires in the harness going through the firewall, and now when I unlock the car I no longer get the illuminated entry (running board lights and interior lights) that I used to get with the factory alarm. The new system has a feature to for illuminated entry via the Aux 1 output, and can be set to trigger these lights when unlocking the car and shut them off after 30 seconds or once the ignition comes on (whichever comes first).
What is the easiest way to regain this feature? Is there a single wire in the factory alarm that I can tap into that will trigger the running board lights and the interior lights? Or do I need to tap into those individual wires elsewhere? I know I'll need to get a power source, fuse, and relay to convert the negative pulse on the Aux 1 output of the new system to a positive power supply, but I just need to know which wire(s) to tap into and where to find them. No diagrams that I have come across provide any information on these wires. Any help would be hugely appreciated!
