I have mapped the 05 and the 12 and am currently lining up the circuits.

Many Circuits are named the same they are just in different pin locations so it is going to require a rewire of the 12 wheel to work with the 05. As of right now it is looking very promising.

The paddles will require a new circuit that passes through the 05 clockspring, but this isn't an issue as there is an open spot. This wire will then feed a regulated voltage to the C3 PCM connection PIN 27 that will allow control of the autostick.

Normal AutoStick voltages are: Down = 0.71 to 1.11 volts, Up = 2.02 to 2.41 volts

All Radio MUX, Cruise Controls and the Dual Stage Driver Air Bag Squibs will work.

The things I'm not so sure about right now are the:
Heated Wheel
Voice recognition
Phone button
Up Arrow
Down Arrow
Right Arrow
Back button
Mode button

These are all controlled by a COM-LIN BUS SCM circuit - 1 C3 D507 22g BK in the 6way connection.
For this I will have to check the stepped voltages and their corresponding funtions. If I can get the voltages to match up with what the 05 wants to see I may be able to activate them or use them for another purpose. If not they will be disabled.

One thing I know I will not be able to get working is the adaptive cruise as we have no front radar and the circuitry for that system is nuts.

I will be able to retain all current 05 functions and have functional paddle shifters. Which will accomplish my main goal.

Huge thanks to Rob for the Mopar connector site!

More work to do Stay tuned!

I see you have a 05 Limited w/ the HEMI. You shound have the Autostick feature the same as I do. If you have the Autostick feature this mod will allow you to control it with the paddle shifters also. If your Jeep doesn't have it I cannot add it as it's in the PCM/TCM's logic circuits. I'm just sending a regulated voltage to the Autostick sense circuit that will command it to shift either up or down depending on said voltage. This mod in no way alters the factory program, it mearly allows you to command it from the steering wheel vs the shifter.

You should have it though and as you have a 05 your wiring will be exactly like mine. Anything besides a 05 and your going to have to check the wiring as it may be different.

I know I can't wait to get it all put together. In tests it already works. I have made the Autostick shift by manually applying the proper voltage to the autostick sense circuit with a voltage regulator and a probe to the circuit. Now I just have to wire the steering wheel paddles to send the proper signal/voltage to the Autostick sense circuit.

James why you must maping all....?

can you not use the same cable from the lx guys and connect it on the shifterbox and go to the steering with the 2 "empty" pins and connect it with the paddles??
If I was using just a set of paddles and my 2005 steering wheel I'm sure I could, but I am using a whole new steering wheel with all new controls (airbag, cruise control circuits, radio mux controls, horn) and adding paddles into the mix.

Everything is wired different and in different locations in the 2012.

So far only 3 circuits will remain the same but those will have to be re-pinned into the 05 connector. The Air bag also has the same circuits but all 4 of their circuits will have to be re-pinned and placed into the 05 connector.

2012 SC circuits:
SC Switch Return - 5 C3 V937 22g GYSC Switch Sense 1 - 6 C3 V371 22g LGSC Switch Sense 2 - 4 C3 V372 22g YL/BK

2005 SC circuits:
SC Switch Signal Return 2 C3 V397 20g VT/BR -2(page 8W-33-2)SC Switch Signal 1 - 3 C3 V371 20g VT/OR -3 (page 8W-33-2)SC Switch Signal 2 - 4 C3 V372 20g OR/VT - 1(page 8W-33-2)


I will have to put the 2012 pins into the 05 connector using this order:

2012 #5 pin into 2005 #2 cavity
2012 #6 pin into 2005 #3 cavity
2012 #4 pin into 2005 #4 cavity

This will match up the circuitry with the 2012 command modules to the 2005 PCM/TCM and provide the proper response when a control is activated.

You are right, I do have auto-stick.What i ment was full control. mine lets me limit the top gear- like every other auto. I cant force it up or keep it from downshifting on its own( i cant lug a gear) Those paddles look sweet, but if I cant MAKE it do what i want/input, then its just pretty.
but,hey,maybe i just have something wrong with mine
True, I have redone my whole shift schedule and at WOT shifts are at 6,500, but it will still downshift on it's own. With the modified trans tune you can make it act exactly how you want. Mine will lug a gear at light throttle (1,050 RPM's at about 40 mph), but if you stomp it flashing the converter and sending it to 15psi all in one act, now that really puts a smile on anyones face. :thumbsup: Well except my wife's...She got :slapfight:and I was like :confused:

My light throttle shift schedule is set to max mpg's (not that I get great mpg's I'm just trying to get out of single digits :lol:). My high throttle schedule is set for power.

All in all though my transmissions logic is the same as yours I just have a built converter, trans, valve body and tuning. So it acts differently.

The good news.

The electronics I can get to work with a bit of rewiring, soldering and a few other modifications.

Horn, Airbag, Stereo, Paddles and Cruise will function. The heated wheel I can get to work but not in conjunction with my heated seats button. It will have it's own switch (a re-purposed one already on the wheel with a bit of reworking). I'm not sure if I even want to mess with the heated wheel though.

The bad, but not so bad news.

Getting the wheel to fit is going to take a dual splined collar insert/adapter. Off to the Fab shop for some CNC time tomorrow.

As seen in the pic below the 05 wheel shaft is quite a bit smaller than the 2012.



Some other pics removing the 05 wheel.







It is possible. It's just going to be a lot of work. But it will be done. :thumbsup:

I was just gonna post this Escape when I saw this thread. I had an SRT wheel to mod for my 2006 and after I took the my SRt wheel off to do research I saw the shafts were different. I didnt even know this thread existed....or I didnt remember. Sorry...I coulda saved you some heartache or you couldve atleast planned for this setback.

No worries. It wouldn't be a true mod without a bit of blood, sweat and a few cuss words...:lol:

I just have to make an adapter sleeve with the 2005 splines on the inside and 2012 splines on the outside. :thumbsup:

I am glad there is a considerable difference between the 2. It makes it easier to make the sleeve. If it was to small of a difference I would have to adapt the whole 2012 steering column, which I have already sourced 38 miles from me.

One way or another it's getting on there.

Dude, much props...you've had to have put hours into checking pinouts, voltages, schematics, etc for something you weren't sure was possible but just had to find out. nice work indeed and I hope it pays off!

Looks like I'll be ordering a 2011 steering column tomorrow.

Anyone out there with either a 2011-12 Grand Cherokee or a new Durango care to post up a picture of their steering column like the one below of my 05 steering column?

all this is was a good read through. like you i was very eager to apply the 012 SRT wheel to the my 010. even if it meant losing a couple functions that are on either or 010&12 wheels.

lot of props for all the effort soo far, thats a lot of leg work handled.


P.s. i almost bought a 2012 SRT8 wheel on ebay several months ago but backed out- glad u got one though!!

400 wheel, 150 column, 4 for the paddle covers, 45 for damper, 4 for the 10mm airbag bolts, 2 for the steering column bolt. The airbag is gonna be the killer at around 600 new.

For just the wheel it lists for $975 new, which is insane. If I didn't find it for a killer deal I wouldn't have done it at all.

If anyone is interested I'll do a write up with pics, parts and cost for those who may want to follow my insanity.

It looks so much nicer sitting there! I'd say it's worth it if you plan on keeping your Jeep forever, modding the hell out of it and find a good deal on the parts.

Is the airbag the same as the non srt wk2? If so it should be easy to find one in a junkyard for a fraction of that price
Yes they are the same. As long as it's in good working condition (like from a mule vehicle) I may go for a used one. I just worry about used life saving devices you know. I want to know it's going to work if I ever need it to.

To be honest, i think a bunch of guys on here, including myself would love to see a write up on your progress with pics. i doubt many would duplicate but, but i wouldnt be surprised if you motivated a couple guys to attempt it once they know it can be done.
Cool! I'll document it and post up once completed.

Today I picked up a 2012 steering column from a Chrysler test mule.

Manual adjust, telescoping and tilting! :thumbsup:

As we can see from my original column there is a steel plate that the column attaches to (pic below). This plate will have to be modified to adapt the new 2012 column. All measurements indicate this should not be an issue, but I may have to weld up a new plate, not sure yet.



Now some pics of the new column I took apart today.









If anyone out there with a WK2 or a new Durango can take a pic of what this (the splined shaft in the pic above) attaches to under the column (there should be an intermediate shaft then a U joint before it goes through the firewall to the top of the steering rack) that would be awesome. :thumbsup:

FYI, becareful there are knee airbags down there.

I'll also be going to my local dealership tomorrow and checking out one of theirs.

As a bonus the steering column will not only be tilt but also telescoping. It also came with the steering wheel damper and bolt.

Now I have to take apart my 05 and see how it all is connected and I'll probably have to weld on some atachments to the 2012 column to allow for the left and right stalks to mount to. I will also have to check the clock spring mounting tabs.

Tear down of mine will be next week sometime.

So far so good, more to come tomorrow. :thumbsup:
