I'm trying to help a friend oiut with their truck ..... does anyone have the wiring diagrams for a F150 manufacture date 9 of 1997
specifically,ignition system and if this truck was equiped with the "PATS"
there is an after market alarm system that is "CREATIVELY " installed by a previous owner..... any help with diagrams or schematics would be helpful
Thank you

 

1997 F150s did not get PATS. 1999 was the first year for that on the F-series trucks..

Go to ebay and order a service DVD or CD for your vehicle. It will have everything you need.
