Can it be used in a 1999 trans am ? And do I need to buy anything else to make it work ?

Hi Brian Hannaway, I'm glad to help you! This MSD Ignition Shift Light, DSL, Adjustable Intensity, for Programmable 7 (Part # 7542) is universal and not vehicle specific. You would have to match one by size to what is in your vehicle that can be fabricated into its place. You will need a Programmable Digital-7 Plus (Part# 7531) to set the standard for programmable ignition control and it is currently unavailable online. I would suggest that you visit the nearest Advance Auto Parts store to check the availability of this part. Please click the below link to view the installation instruction about this product.
