    I looked at my 93 Caravan, You really need the shop service manual.
    There you can find the leads.

    In any case, on my 93, There is a sealed plug with two wires that plug
    into the transmission. This plug is located inside the engine
    compartment, on the drivers side, facing the front and very low, you
    have to reach way down to get at it.

    I forget the colors of the wires, There are a number of plugs in the
    same area.

    If you unplug it and drive a very short distance, the speedo will not
    work. Your transmission will behave strangely as well, so drive it
    only a few feet to varify the speedo not working.

    One of those two wires is what you are probably looking for. But if
    you are splicing into them, make sure you seal them up tight against
    water, This plug is near the road so it sees a lot of water and dirt.

    This wire goes right to the computer. The speedo and all the
    instruments are driven from the computer to the instrument cluster via
    a bus so you don't have access to the speed data, except right at this
    speed sensor.

    Be carefull with this, you don't want to blow your computer, it is big
    bucks to replace.

  3. Most GPS units are quite capable of computing a pretty accurate speed
    themselves.I'm curious, what does the Kenwood GPS use the speed sensor
    signal for? Unless the GPS you are referring to isn't Global
    Positioning Satellite.

    Your engine management system will log a fault for speedo sender not
    working, which will still be there next time someone looks at the fault
    codes. Remember to clear the computer or ask your mechanic to do so
    after you do this to avoid future confusion...

    Some automotive GPS units use a connection to the speedometer cable (and
    sometimes other parts of the car wiring) so they can still make a guess as
    to your position when the satellite signals are temporarily blocked, e.g.
    by tall buildings or when going through a tunnel.

  7. Why does the subject line say GPS if you are hooking up a DVD unit? My
    guess for the speed sensor for a DVD player would be to allow the volume
    to increase with speed. My motorcycle radio/cassette player works this
    way. The faster I go the louder the volume gets. My unit has a gain
    control to allow me to select just how fast the volume ramps with speed.
    Does your Kenwood have such a control? If it does, then this is very
    likely the purpose of the speed sensor input.

  8. Thanks, that makes sense. I'm used to GPS in airplanes where being
    blocked by buildings or tunnels isn't a problem. If my GPS gets blocked
    by either of those, then loss of position is the least of my problems...

  9. Most GPS built in units have a form of dead reckoning for tunnels etc.
    This is part of why they cost so much more.

    I think the speed sensor is to alert the GPS system to stop operate
    like ...dead reckoning for tunnels etc ... so the map will not move
    around and stop the GPS to search where I'm located, that's way I need
    to connect to the speed sensor, but up to now still can't locate the
    speed sensor wire yet.

    Look here for why its called a GPS DVD system

    REMOVE the NOCRAP in my address to reply.

  14. The Kenwood instructions don't tell you where to find it?

    Just a couple of small clues:


    - Dual-Layered DVD Disc
    - DVD-ROM Player: 2x Speed
    - Kenwood-Developed DVD-ROM Mechanism


    - Included DVD Contains Maps for Entire Continental USA and Canada

    Kenwood KNA-DV2100 instruction diagram shows a wire to connect to
    speed sensor, that's it, that's why I'm looking for the 95 Caravan
    speed sensor location ... H. Ham

  18. Probably best to visit your local Chrysler dealer and ask them.

    W/O EAT:
    ORG = 5 V supply
    WHT/ORN = VSS Signal

    VSS Signal at PCM is still WHT/ORN
