2007 to 2012 Steering Wheel Swap

Monkeyporn · Apr 9, 2020

OK I've read tons of forums on how to do this and I know I need two 440 plugs and a PAC those I think I can get most anywhere. However I also need a 100mvh resistor that i have no idea where to get. I also have some concern about sobering said resistor in line. My concern is that I read somewhere that it had to go in line in a cetain direction. Thats where I need help is with the installation of the resistor. Anyone who knows how or has done this swap that could give me some guidance I'd be greatful. Electronics is not in my wheel house I'm more of a nuts and bolts kinda girl.

Is this to get the radio controls working? For the cruise control you just need to repin the harness. As for a resistor, they're measured in Ohms of resistance, and do not need to be in a certain direction, they have no polarity. As for soldering the resistor just wrap the wire around the stem and hit it with some solder, does not need to be perfect. If you have some kind of wiring diagram talking about the pinout I can help some more.

Macman thanks for responding and thanks for the 411 on resistors. To answer your question YES this is to get the radio controls to work. Can you please tell me what kind of resistor I need all the forums I've read say is 100Ohms resistor. I'm game to give this a try myself but I will admit I'm nervous about the whole thing.

It probably is the 100Ω resistors, this is to decrease the current flow in the circuit and not short out the headunit. Which headunit are you installing? Usually the PAC is anticipating some sort of voltage drop, not a short circuit like the 2012 steering wheel is willing to give. 100Ω is safe and will either be perfect or just not work, as the tolerance is usually 5%, so as low as 95Ω. I highly doubt you'll damage anything its a low voltage circuit. As for the resistor you don't need anything fancy other than am axial, probably carbon or metal film resistor. I think you need one for each switch you want working (Vol + Vol - next previous etc etc) so probably half a dozen at least. This should do you:

Note: Half a watt heat dissipation is fineee, on a 12v line that is 42mA, I'm sure it's less being a switch.

Start there. Post up the headunit you're trying to wire in and whatever pinout you've found for the PAC

Yea, please do. It is time for a boss steering wheel swap in my 07 gt and a touch screen head unit.

Cruise control will not work. The resistance values are different between 07. & '12. This could be, in theory, fixed in the tune. But we dont get access to change the cc resistor values.

Proof: I am running the 07 (original to car) steering wheel. When I run a tune based on the KWC4 strategy, no cruise control. Live data shows the switches working, but register incorrectly.
With nothing other than loading the Crate6 tune, I have cruise control working, and all the cruise buttons register correctly in live view of the pcm.

Solution: use the 07 cc buttons in the 2012 wheel if possible.

My car does not have radio control on the wheel.

Macman Thanks It was my understanding from the forum that the point of the one resistor was so the PAC could distinguish voltages between the cruise and radio buttons. As to the headunit I have alrerady installed it. It is a Pioneer AVH-W6500NEX. I see you have provided a RadioShack link I didn't known there where anymore Radioshacks.

Probably not brick and mortar but I still online order. You can find the same resistors from digakey or Mouser online

In theory this should be easily fixed with an inline resistor. Put a multimeter across the 07 switch, get it's value in ohms, then repeat on the '12 switch. Whatever the different is, add that resistor in series. Unless the 07 is less then put in parallel LOL.

True, but I was unable to find the actual cc switch resistance values for a 2013. (My pcm model year) And then I find the cruise working with the Ford Racing crate calibration. lol. Ford told me it did not support cruise...hmmmm so they were wrong

Hmm interesting. Yes im sure you could change the parameters in the tune for the software to look for a different resistance value to close. Should also work by shunting the circuit physically. Curious what the resistances of the two come back as!

Not worth my effort. I like the ford racing cal vs modified stock gt cal. Makes more power, drives better, and have cc. Im good.

SCT does not have the resistance values mapped in PRP. And from what I read, neither does HPT

Who says cruise buttons won’t work? They work fine on my 06. I just swapped out the harness plug from the original wheel to the new harness on a newer GT500 wheel. No resistors needed. All cruise buttons and the backlight works just fine.

I agree with you. I don’t think you need any resistors for the cruise. Juice was doing a coyote swap I don’t think he realized it was just the steering wheel

Wait so your saying I DON'T need the 100Ohm resistor ? OK now I'm really getting confused. Eletronics is not my forte so I'm doing my best to understand this and do what I need to install the GT500 wheel myself, but it's getting more confusing by the second.Iy is my understanding that the 100Ohm resisitor goes on the Radio button side.

Ignore the cruise control stuff. I bet it just works. the RADIO buttons need the resistors.
