    Hi dd_ellington,

    Your vehicle is covered in Haynes manual no. 24071. The wiring diagram for the backup lights is on page 12-44.

    If you get the manual and still need help, contact one of our tech service reps at [email]research@haynes.com[/email].

    Thanks for your interest in Haynes manuals!
