i did a write-up for adding factory heated seat to my '09 challenger. i am not sure if the other cars are prewired for the dash switches like the challengers are. also, the challenger seats are prewired for the heating pads. again, not sure about the other cars.
anyways, here is the write-up on the challengertalk forum. note that this mod requires programming to enable the heated seat module. i am not sure if the dealer can do this with the JPM sales code or not. if not, there are only a handfull of us around here that can do the programming for this.
if info is needed on how to add the wiring for the heated seat dash switches, i will add it.
okay, here is the info on how to add the wiring for the heated seat switches if your car isn't prewired like my challenger.
here are the needed pigtails cut from a donor car. you need a length from the clusters C3 white 26-way connector, a length from the left heated seat switch, and a length from the right heated seat switch.
now, you need to connect the switch pigtails to the clusters C3 connector. make this custom harness 36" long connector to connector. splice these wires together:
C3 pin #7 --> left switch pin #4 (tan w/white stripe wire)
C3 pin #9 --> left switch pin #6 (tan w/light blue stripe wire)
C3 pin #10 -> right switch pin #4 (tan w/violet stripe wire)
C3 pin #18 -> left switch pin #3 (light green w/grey stripe wire)
C3 pin #19 -> right switch pin #3 (light green w/light blue stripe wire)
C3 pin #22 -> right switch pin #6 (tan w/dark green stripe wire)
start with splicing these 6 wires from the cluster connector to the left and right switch connectors.
here is another view of the new harness for the heated seat dash switches.
next, join the black w/green stripe ground wires (pins #2) of each switch connector together, lengthen and put an eyelet connector on it.
then, join the red w/orange stripe fused B(+) wires (pins #1) of each switch connector together, lengthen....
finally, join the orange w/grey stripe wires (pins #7) of each switch connector together, lengthen....
here is a close-up of the white 26-way connector from the cluster. pin #1 is labeled for you in this pic.
here is the harness all taped up. it is still connected to the donor 26-way connector.
next, remove the pins from the 26-way connector. we only need the metal tabs from those 6 wires.
these are the cavities we will be adding wires to on your existing 26-way connector. the wire in pin #11 will need to be spliced onto.
here is the completed wire harness for the switches. it is ready to install in your car now.
to install this harness, just plug in those 6 wires into your existing 26-way cluster connector
then splice the orange w/grey stripe wire onto the orange w/grey stripe wire in pin #11
then ground the eyelet to the dashes metal framework
finally tap the red w/orange wire to an existing red w/orange stripe wire under then dash.

Nice work buddy. I did mine in January outside so I didn't take pics. Here is how I did it in a 06 300.
The older cars dont have the wiring in the dash but they work without programming ( just wont back light). Correction they will back light I had 2 bad switches and programming may be needed on some models.

just added the info needed if your car isn't prewired for the heated seat dash switches. the instructions are pretty much the same as what dennis did for his 300. you can follow the link on CT to complete the install as i did on my challenger.
Great job as always Tony.
From wild to extra wild we got you covered with crap ya never knew you needed.

Well I just finished adding factory heated seats to my '06 magnum sxt. Unlike Dennis's car, mine required programming to make them work. I tried it before I programmed just to test this. The seats did nothing and I got a DTC for additional ECU detected. Pretty much what I expected. Any time to wire in a new module to the can bus system it requires programming.
Why Dennis's car worked without programming, I don't know.
Most likely because my EVIC cluster came from a car with heated seats.
