Alarm kill switch doesn't disable anymore.

I posted a thread in the 5.0L forum but didn't find much help, so I'll try here before trying to tackle the problem myself.

My car only starts from bridging the solenoid terminals now.
I feel that it is the alarm kill switch, but I have no idea how to work this thing and which wires are for what. Does anyone know how to reset this or help me point out the wires for the kill switch or tell me how to find it so I can bridge it and bypass it? The killswitch stopped working when I switched out the battery on my main keyfob, so I think that has something to do with it. Would I have to rebind my alarm key control? It still unlocks the car and locks it, it just won't disable the killswitch. I have another spare set of keys with the keyfob and that won't disable the killswitch anymore.

My alarm is an aftermarket Gravity, with Keyless Entry, Shock Sensor, Kill Switch (not to fuel pump but ignition since I can start through solenoid fine)

Attached are pictures of my wiring. Hope someone is familiar with my alarm system or can tell me how to bypass, I'd like to keep the killswitch function since it is a pretty nice anti-theft device, but if I have to bypass it that is fine by me.

Go to the ignition wiring section the heavy gauge wires coming out of the key and look for the WHITE/ PINK wire this is the starter wire follow this 2 wires same color to the alarm you are going to find a relay
unplug both wires from the relay and connect them together using a 15 to 25 amp fuse and try to start the vehicle with the key, if it works replace the relay,
if you have the same problem leave the alarm alone the problem is not there
