Lisa, you have a 01 Trac. So, it can be in one of two locations.
If you have a Job 1 (Early production date) it will be located behind the back panel behind the rear seats. Once you remove the panel you will see a module there with the 5 digit code.
If you have a Job 2. It is located behind the passengers air bag. Some have been able to remove the glove box and get the numbers with a mirror, most have had to remove the air bag to see the numbers. Keep in mind that if you use a mirror the numbers will be backwards. So a 2 will look like a 5....
