Wire Location? Turn Signal Mirror Accessory

I'm trying to add turn signal mirror parts to my 04 Chrysler mini-van. It is
widely reported that these 04+ vehicles are factory wired for these parts.
Yet, when I pull off one factory mirror I only found 5 wires, 2 for the
mirror heater and 3 for the remote motor. I found no wires for the signal
lights. Anyone have any information on this issue? Thanks

Hey Richard,

I don't believe they are pre-wired in the mirror. You'll have to
connect to the turn indicator circuit in the vehicle. Didn't your
accessory come with instructions? How about contacting your dealership
for more wiring info on your Chrysler?

I'm not using the Chrysler red arrow on the mirror kit. Instead I purchased
a left and right mirror amber LED indicator module used on the outside of
the mirror housing of Mercedes models. [I picked up the smaller unit used in
2000 E220 models]. I intend to cut an opening into my housing and glue the
LED module's in. I had read that 2004 mini-vans had the guts pre-wired but I
guess that report was in error.

pick up the signal at the front turn signal lites not under the dash run wires to
the mirrors

 

I think that may be more difficult than just routing the wires
internally because of the way the wiring for the mirrors is set up.
When you fish the wire into the vehicle from the mirror, it's already
inside the passenger compartment so you'd have to then find a place to
fish the wire out to the headlamps, which seems to be an extra step
when compared to just connecting to the wiring under the dash...

Be sure to solder and shrink-wrap the connection to avoid corrosion,
especially if you connect on the outside of the vehicle.

you are correct about the amount of work but the liting system on the vehicle is a
multuiplexed system and tapping into the switchand wiring there will cause all sorts of
problems and it will set all sorts of fault codes in the bcm and ipm, if not right out
failure of these modules unless u know how to add resistors and relays to covert the
signals

 

Richard,

Years ago the factory would use 1 wire loom for every model - it would be
wired with all of the accessories, whether they were actually installed or
not
in the car.

Today the factory inventories at least a dozen different wire looms and
they only
run wires for the accessories that are ordered when the vehicle is built.

I'm not advocating tearing into the steering column to make the
connection, just connecting to the same circuit you are directing him
to only on the inside of the vehicle before it exits to the exterior.
This will skip the step of rerouting the wires to the outside. If that
will cause a problem on the inside, it will cause one on the outside
too, right?

Mopar sells a signal mirror kit for this vehicle and the instructions
show to make the connection in the vehicle. Mopar part and Mopar
instructions. Kit number is 82208727 if you're wondering. That's how
the factory says to do it too...
