Go to Auto Zone online. sign up with them and get free access to some very good online All-Data manuals. They are not the cheap chilton stuff either

Select your truck and part form the part list,some place on the page will be a link to a diagram and how to install it . Auto Zone uses AllData online now. but I know I was going to sign up with them for 56.00 a year. Until some one told me AutoZone uses them too. You get for it free when you sign up on line with AutoZone . you Don't have to buy anything though. all autozone ask for is an email address. they don't spam you either. as matter of i never get anything from them . I do get order conformations when I order oil and stuff like that to pick up at the store. or a hard part I cant find to pick up.
