    Definitely will do! I was planning on taking the pictures for a more up to date how to posting if it worked.

    Small update:
    I’ll need to find the reverse wire. Got into the secret menu and REV says “off” while in reverse.

    Here's what I had to do to put a 2006 High-res MFD in my 2004 basic Prius.
    (The pins on the diagram for "B" in 2006 matched the pins on my basic 2004 -- a 2008 may be different.)

    Here is where the Reverse signal should be: (again, from a 2006, so 2008 may be different) this connector is vertical in the car, behind the air vent dash trim to the right of the radio in a US car. (*This is probably missing on a basic Prius AND a lot of wires to contend with, it may be simpler to just go to the J10 connector mentioned in the next post.)

    If you don't have the Red wire at 5N, pin 14 in Connector 2, then the Red wire(s) at A in connector J10 in the passenger kick panel area (in a US Prius) is the switched 12v+ going to the backup lights. (And, where the Red wire to Connector 2 should have come from!) --Always check with a meter to verify voltage/signal!

    Here is the wiring diagram for the reverse signal to the 2006 MFD (Note that the J10 connector also sends the Backup voltage down to the backup lights on that Red wire. Do not power the camera from here! The camera must be "sensed" by the MFD during its "boot up", so it is best to use the power pins it provides, M14 pin 27 (V+) and pin 28 (V-) (I would also add an inline fuse to the camera V+ wire coming out of the M13 connector at the MFD, so I wouldn't harm the MFD if I shorted the wire by accident.))

    This is a good picture of the connectors (connectors mislabeled in this picture, these are M14 and M13)

    from the earlier post #52 in this thread.
    (I got my missing M14 connector with the 2006 MFD from the junkyard.)
    If you are missing some of the wires and pin connectors, another thread mentioned that the old audio connector from a CD in an older computer is a good "donor". (Keep the video signal shielded as much as possible before splitting out to the connector wires.)

    ItBland,
    Thank you! I’m going to print this out and study this.

    I didn’t realize it was going to be this involved. I’m too far in this project, I have to complete it now!

    I have a feeling I’ll post back asking some more questions.

    You should probably ignore post #104 above, and just go for the wire in connector J10 for the reverse signal, much easier to get to and much easier to work with fewer wires. Also the picture in #106 is only valuable if you like to look at schematics, it really doesn't add anything. However, some have found out the hard way that if you try to power the camera from the reverse lights. it won't work with the MFD, so adding that advice was the good part of that post. Also, if you don't have an M14 connector (and can't find one in a junkyard) the CD connector (shown in #107) can be used--it has the correct spacing for the four camera pins on the back of the MFD.
