need to disable kill switch

Fellas,

     I have an older alarm system on my truck, about 8 yrs old. The brand name of the system is "Lone Star". I haven't used the alarm in quite a while and it is now giving me some problems. I have kept the system on "valet" mode because my keypad has gone to hell.  This morning I noticed that the red signal light was off, not on like usual.  Then ,while I was driving the kill switch activated and totally diabled my truck, while it was in motion going down the street. Then the alarm activated and I had to disconnect my new battery and then reset the alarm to the valet mode. I assume that reset the relay and it starts and runs fine now. 

This all creates a huge saftey issue  with me and I need to totally disable the alarm if not outright remove the whole system. The local alarm techs are no help, they just want money that I don't have. Could someone please give me some step by step instructions of how to atleast diable the kill switch.

Thanks alot,

JD

I may have got it.

I pulled the dash and found the brain. On one side had a mass connection and on another side is where the valet switch is hooked up, then next to the valet connection was a connection with a black and a red wire . I traced that to the ingnition switch and decided to disconnect it from the brain. When I did that, there was no activity with the alarm at all. I took it for a drive and it went well.

But is the kill switch /relay usually contained inside the brain or along the wiring? Is there anything else I need to know?
