I have a TRC security system in my 2001 Dodge Ram. It uses a remote #90REM4. I bought this truck used. Can anyone tell me where I can obtain the instruction manual on this alarm system. I need to know what this alarm system is capable of. Right now I have a hard time getting it in and out of valet because I don't know the right procedure. The TRC website is useless. They only cater to dealers. I did find that the remote is for one of four systems that they have. I don't even know where to find the sysem I have. Anyway, the systems are, 90903 90945 90983 90912
