  1. Mo, as much as we would like to help you, not all car alarms are installed the same way. Different brands and different setups will call for different wiring. Our advice is to take your car to a qualified alarm installer and ask them find the valet switch because it does take some alarm wiring experience to know what to look for. Hope this helps. Good luck on your 1998 Toyota Avalon alarm troubleshooting.
