Adding Steering Wheel Controls to Xterra

I added steering wheel controls to my 2010 Xterra today and have pics and write up to finish for it. Im going to load the pictures on my website for the time being then if someone would like to host them and put them on the forum so they are permanently saved that would be great. (Im not a computer guy just a car guy)

Parts needed:
2552-EA08A Description : Switch Assembly Cost $81.72


This comes with both the left and right side switches on the steering wheel which you need to make this a simpler install.

Need Pac adapter or Axxess. Depending on what you like to use.

I used a Pac SWI-JACK
12v Ign - Red
Ground - Black
Interface Wire - White
(tape all other wires)

There is 2 8 pin plugs to be concerned with for the install.

The airbag side and the steering column side. (Airbag means under the airbag, steering column means car side closer to the pedals.)

Step 1.
Remove Battery Negative Terminal and touch to the positive to discharge.

Step 2.
Remove door sill, kick panel, under dash, steering column cover.

Step 3.
Remove airbag using a flat head to push up on the metal bar you see threw the small hole under the steering wheel. If the airbag does not release push on it as if you were honking the horn while pushing up on the metal bar.

Step 4.
Unplug and Unscrew the 2 torque screws holding the left and right side buttons on. Notice how the wires are routed behind the shroud for later.






Step 5.
You must de-pin all of the wires from the factory switch for use later on. Remove the back tab on the plug then use a small pick in the front to push the wires out.


Step 6.
The airbag 8 pin plug must be repinned. The upper edge is #1 and so on down to #8
#1 Blue
#2 White
#3 Yellow
#4 Brown
#5 x
#6 x
#7 Black
#8 Red


If you are doing illuminated controls your harness should look like this.
The airbag 8 pin plug must be repinned. The upper edge is #1 and so on down to #8
#1 Blue
#2 White
#3 Yellow
#4 Brown
#5 Pink
#6 Yellow
#7 Black
#8 Red


Step 9.
Install the new switch panels and torque screws and plug it in once the plug has been pinned correctly and put back together.

Step 10.
The steering column plug. You must add 1 wire from the plug you originally removed. I used the thin red wire.

#1 empty (pin this pin with the thin red wire)
#2 brown
#3 red
#4 green
#5 empty
#6 empty
#7 black
#8 light blue
You will have 2 spots left open. These are for the illuminated controls, see below.

or for illuminated controls.
#1 empty (pin this pin with the thin red wire)
#2 brown
#3 red
#4 green
#5 empty (pin with a wire from factory harness)
#6 empty (pin with a wire from factory harness)
#7 black
#8 light blue



(remember the numbers are just for reference, they do not go in order on the top to the bottom they are very unorganized for some reason. is comes out like this.)

Top - Bottom (colors)
blue - green
white - thin red
yellow or green w/ Plug- brown (Horn)
Brown - red
empty - empty
empty - empty
black - black (cruise)
red - lt blue (cruise)

Illuminated controls!!!!!
Top - Bottom (colors)
blue - green
white - thin red
yellow or green w/ Plug- brown (Horn)
Brown - red
pink - this wire you pinned goes to ground*
yellow - this wire you pinned goes to illumination wire*
black - black (cruise)
red - lt blue (cruise)

* if they do not illuminate switch the ground and power and let me know so I can update. *

Step 11.
Cut the Red and Green away from the car leaving about 2 inches of slack to work with. You should also have the this red you pinned in hanging as well.

Thin red 150 ohm resistor
Green 47 ohm resistor
Red - Ground this wire.


Step 12. Put the steering wheel airbag area back together remember to connect the horn wire.



Step 13. Connect the battery.

Step 14.
Connect the 2 wires with the resistors to the white wire of the pac interface. Then program your interface.

Everything should work fine. It works great on mine.

I will be doing this install at my shop. With parts its $325 installed. May seem like a lot but this is time consuming.





Pictures will be added shortly.

(Next write up alarm / remote start already finished it just need to type the writeup. )

Just for simplicity of it, your wires dont have to match mine at all as long as you know which ones are up top and which ones are under. If you know which one is the horn behind the airbag and which one is horn at the steering column you know what to do with it. I had to do a lot of testing with a meter to get it all right but in the end its a matter of just knowing top and bottom.

Resistance Type Control System YES
Reference Ground Wire Color ORANGE
Reference Ground Polarity (-)
Reference Ground Location RADIO HARNESS
Reference Ground Pin # 3
Control Wire 1 Wire Color VIOLET
Control Wire 1 Polarity (-)
Control Wire 1 Location RADIO HARNESS
Control Wire 1 Pin # 4
Control Wire 2 Wire Color LIGHT GREEN
Control Wire 2 Polarity (-)
Control Wire 2 Location RADIO HARNESS
Control Wire 2 Pin # 12

These are all based on my pictures.
(the first 2 wires may need to be switched I havent done the axxess unit yet)
Connect the gray/red to pin 4 (violet) on factory harness or green on steering column harness
Connect the white/green to pin 12 ( lt green) on factory harness or thin red on steering column harness
Connect pin 3 (orange to ground on factory harness or red from steering column


[programming is here] http://documents.victorytechnologies...icle/10979.pdf

I leave for canada tomorrow so post up tonight so I an help since I have my diagram at the house.



Or email me [email protected] it will go right to my phone and remind me tonight


Also editing this to make it easier

If you are doing illuminated controls your harness should look like this.
The airbag 8 pin plug must be repinned. The upper edge is #1 and so on down to #8
***(The lower harness does not match up 1-8 it is random so here is how it matches)***

pin#1 Blue (steering wheel control resisted reference wire #2) pin #4 green wire from factory
pin#2 White (steering wheel control resisted reference wire #2) pin #1 thin red I added
pin#3 Yellow or Green (horn) pin #2 brown factory wire (Horn wire)
pin#4 Brown (steering wheel control ground reference wire) pin #3 factory red wire cut and ground
pin#5 Pink (illumination ground) #5 Pin with your wire
pin#6 Yellow (illumination +) #6 pin with your wire
pin#7 Black (cruise) pin#7 should not have to touch
pin#8 Red (cruise) pin #8 should not have to touch

Sorry its so much easier to do then to put on paper. My mind is a vault when it comes to doing this stuff and I can visualize it and do it but when it comes to explaining it I have a hard time.

Will the interface allow the bluetooth/phone buttons to be used if you add an aftermarket headunit with bluetooth?

Nice man! Great write up.

For those who are thinking about doing this...definitely use the AXXESS ASWC steering wheel interface. The PAC unit requires resistors, programming, and lags when you press the buttons and when the radio does what you want it to do. The ASWC is a simple 3 wire hook up, no resistors, no programming, and zero lag (just as fast as OEM controls).

According to PAC's programming options..there is nothing about programming bluetooth controls. However, I have heard from some sources that it can. I have never confirmed/denied this though. The AXXESS ASWC will but only on certain decks. I can only speak for my setup and I have a Pioneer AVH-P3200BT that has bluetooth and I have the ASWC interface and it does NOT do the bluetooth controls even when I manually programmed it. Other decks it may. You'd have to shoot AXXESS an email.

EDIT: Just saw this on PAC's website:
Quote:
Product Revision History

Current Revision #: 1.6.8 Description: Adds voice recognition support for Pioneeer

Revision #: 1.6.7 Description: Adds Bluetooth support for Pioneeer
Apparently the PAC unit will do bluetooth controls now?? They say it will...guess you'll have to be the Guinea Pig.

I dont have any lag on my headunit with the pac piece.

The bluetooth doesnt have any control on my unit except mute and volume of course.

Why do you have to re-pin the airbag harness?

Is it the actual airbag you are re-wiring, or is it just a harness that is called the "airbag" harness? It would make me nervous to mess with the actual airbag wiring.

I'm pretty certain that's not the actual air-bag harness. All airbag wiring has yellow loom/tape around it for easy identification. I could be wrong though....
