here is how i added the remote steering wheel switches.

here are the switches needed:

for the '05-'06 silver switches, part #UZ56XZAAC and #UZ57XZAAC
for the '07-'09 black switches, part #UZ561ZAAD and #UZ571ZAAD

i used the silver switches because i thought they match better. here is a picture of the new switches and the stock steering wheel plugs. you don't need to change you steering wheel to add the switches. you only need the switches.



here is the pigtail wire harness that connects the switches to the clockspring.

harness part #68039387AA

as you can see the new harness compared to the old harness without the switches. the new harness plugs into the stock clockspring. all clocksprings are the same so no need to change that.


here is the interface module needed. part number #68034920AA
sometimes this is called the steering control module (SCM) whatever the name is, here is what it looks like.



now that you have all of the hardware, i will try to explain how to install it correctly. first, start by disconnecting the negative battery post. then after a few minutes, you can start to disassemble the steering wheel. start by fully extent out the adjustable steering column. then remove the airbag. there are two 10mm bolts holding it in. disconnect the horn and airbag wires and move the airbag off to the side somewhere. disconnect the stock wire harness from the clockspring pigtail and cruise stalk and toss it. the steering wheel spoke plugs can now be removed. i just used a small flat blade screwdriver to get them to pop out.

your steering wheel shoud look like this now.



next, remove the steering wheel retaining bolt and slide the wheel off the shaft.



now comes the scary part. that black disk with the pigtail sticking out out it is the clockspring. it is very easy to damage and very costly to replace. there are three torx screws holding it in. back out the screws one at a time. back them out enough to keep the clockspring from spinning. you do not want it to unwind of get out of center. the screws will stay in the lower half and stick out of the upper half to keep it from spinning. once the three screws are out enough to hold the halfs, carefully pull the clockspring straight out. look at this picture. you can see what i mean about the three screws sticking out to keep it from spinning and why you need to pull it straight out as not to bend any of the prongs.



next, back out the set screw through the access hole on the steering column.


then lift the whole SCCM off the shaft.




then bring the SCCM unit to a table to disassemble.



here is the disassembled unit. and the new SCM.



swap out the SCM with the new one and reassemble the SCCM unit.



now, you can reinstall the SCCM on the steering column and tighten the one setscrew. now, very carefully push the clockspring back and make sure the prongs are all straight beforehand. push it in until it bottoms out on the SCCM unit. tighted the three torx screws. align the spline on the steering wheel hub to the shaft and install the retaining bolt to 52 ft lbs.

to be continued...

once the steering wheel is back on, you can add the new wire harness and switches to the whee. route the wires like this. look at these photos carefully to see the correct routing.






next, get the airbag and plug in the horn wires and the two for the bag and install it back on the wheel. install the last two 10mm bolts for the bag. that is all there is as far as the hardware goes. it should all look factory stock like this.



next, will be the programming. i programmed it myself with firebird2000's help. i used his starMobile. But, there are sales codes for the steering wheel remote switches and EVIC display. i didn't use the sales codes to update the vehicles configuration so i can't guarantee they will work. here are the sales code the dealer needs to get chrysler to reconfigure the vehicle for the added feature.

sales code LAZ is for the EVIC
sales code RDZ is for the remote steering wheel switches.

once the programming is done, the switches will light up and come to life. they will control the radio and let you scroll through the EVIC display in the cluster. if you still have the stock cluster without the EVIC display, the switches still control that cluster. it will only scroll through the odometer, trip, and temp display because that is all that is in there. to add the EVIC cluster, you will also need to add the Homelink setup. i did a write-up already to show this. here is a link

How to install factory Homelink




good luck with the project guys. here is a link to that custom Hurst shifter mod too.

Wow, nice write-up! I am not that brave enough to go and take off the steering wheel for this upgrade. Although I want it bad.

I just did my wifes new 2010 RT Classic all it needed was the wiring harness and for a dealer to install the sales code. No need to change anything else. Her car came with the cheaper radio which I replace with Mygig. The buttons work with any Dodge factory radio that comes in the Challenger.
