(RPO) Codes -(Regular Production Option); 
 There is a white sticker on the inside of your glove box that lists all option (RPO) Codes (these codes were referred to when your truck was built); listed in numeric and alphabetic order. They are a series of letters and numbers formatted with how your vehicle was built. This particular Four Wheel Drive Selector Switch works with option code NP1 only (which you should find on your RPO Sticker).
