    I have a couple of questions 1 of them is can this be used on a 97 f150 even tho it says it's for a 99 and up and will this also run the transmission I tell to make it work properly

    Asked by: Sparkplug110
    You will need to modify the wiring harness and add the required sensors to make it work on a 1997, it is designed for the 99 and later applications.
