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

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...
Thanks Steve, I'll try to locate it tomorrow, thanks again for your
Matt, mine is a Kenwood KNA-DV2100,it's a 2002 DVD unit, the system do
require to connect a wire to the speed sensor, dont know ... please

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.
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...
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.
Looks neat, but I didn't see any referenct to a "DVD unit" as mentioned
above. Looks like only a navigation system, from what I read at the

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
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
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.
