How to connect the GPS to speed sensor in '95 Caravan ?

I got a used Kenwood GPS, would like to install on my 95 Caravan, need
help to locate the wire to connect the GPS to the speed sensor ...
thanks for the help

 

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.

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...

 

Thanks Steve, I'll try to locate it tomorrow, thanks again for your
help.

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
advise, thanks

 

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.

 

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.


Matt

 

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...

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

"... Kenwood KNA DV2100 GPS Receiver ..."

 

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.

 

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
link above.


Matt

 

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

Matt

 

Much better link. Looks neat.


Matt

 

Just a couple of small clues:


DVD FEATURES

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


NAVIGATION FEATURES

- 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

 

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

W/O EAT:
ORG = 5 V supply
BLK/LT BLU = GND
WHT/ORN = VSS Signal

W/EAT:
VSS Signal at PCM is still WHT/ORN
