    Is yours an early car without Cruise Control?

    There was a thread a while ago regarding this:

    If you’re trying to add cruise control to a car that wasn’t built with it, see these previous threads:

    Adding cruise switch to basic version | PriusChat

    The CCS terminal on the hybrid vehicle control ECU is F3-14. I don’t know of a terminal called ECCS; the ground connection for the cruise control switch, ECC, is from F21-2 to ground point FA, all shown in the Electronic Technical Manual from which the printout in your image “p6 (1).jpg” was taken.

    As I wrote previously, however, I don’t know if adding the switch and wiring is enough to enable cruise control on fourth-generation (ZVW5#) Prius cars, as it was on other models. If it works, please do let us know.
    I’m afraid there are very few exhaustive answers, mine included, in this forum. The people who could give such answers work for Toyota and its suppliers, and as far as I know, don’t post here.
