How to install steering wheel audio controls

This is a how-to on installing steering wheel audio controls in a truck that didn't come with them from the factory. It is only for using them with a PAC adapter and an aftermarket headunit. It's not for those that want to add the factory six disc. I never had that and I don't know anything about it. So far I've added these to my Frontier, my wifes Pathfinder and my sisters Xterra. My truck is a 2005 LE crew cab 4x4. They all use the same wires. Just make sure your aftermarket headunit has an OE REMOTE input on the back.
Tools you'll need-
Phillips head screwdriver
T-15 torx screwdriver
Small flathead screwdriver
Medium sized flathead screwdriver
Wire cutters
crimper.
Parts you'll need-
The steering wheel controls PN 25550NA from courtesy parts- $69.02 shipped
A PAC adapter for your radio make. Mine were alpine & Pioneer about $45 ea
22 gauge crimp connectors.
Step 1: Disconnect battery and let it sit for 5 minutes.

Step 2: Remove old cruise control switch.
start on the bottom in the middle of the wheel there is a hole with a metal tab in there. Gently push it up with a screwdriver. This will release the airbag and it will pull out.



Step 3: Using T-15 torx driver unscrew blank cover on left side of wheel and remove.



Step 4: Using T-15 torx driver unscrew old cruise switch cover and remove.



Step 5: Disconnect connector in steering wheel. And your old stuff is out.


Step 6: Install new cruise switch and screw in.


Step 7: Install new audio control and screw in.


Step 8: Plug in new wiring connector and tuck the cable between the two behind the metal tab. You had to pull it out of there to get the old one out. It's just tucked in there to get it out of the way.


Step 9: Double check that you plugged everything in and screwed everything down and reinstall the airbag. I just held mine while I was doing this so I didn't have to disconnect it or have it hanging by it's cables. You just push on the airbag until it snaps in.



Step 10: Take your old cruise switch to the work bech and remove a small plastic tab from the side of the connector. This will let you pull the wires out. I had trouble the second time I did this and ended up just cutting the plastic. You want the three connector pins from inside it so try not to damage them. And you want enough wire on them to be able to connect a new wire.




Step 10: If you didn't already have it out. You have to remove the kickpanel and lower dash panel under the steering wheel to get the lower steering wheel column cover off.

Step 11: You have to remove 3 screws from the bottom of the column cover and then use the small screwdriver to gently pry them apart. Now you have access to the connector on the bottom of the steering wheel. It's the gray one not the yellow. The yellow is for the airbags.






Step 12: Now it's time to wire up the infamous PAC switch. In this case the PAC-SWCPS going to an AVIC-D3. You start out with your wiring harness. Pull the red wire, black wire and white wire off to the side and fold up and retie all the others as they wont be used. Get your 150 ohm and 47 ohm resistors ready.


Step 13: Next crimp the 47 and 150 ohm resistors onto the WHITE wire. Then put another butt connector on the end of each resistor.


Step 14: Remember those pins you took out of the grey connector from the old cruise control? You take the connector on the back of the steering wheel out and there is a small white tab on the side. Pop this out a little bit and insert your wires into the three empty slots on the top row left side. Here's a picture from my last thread about this. In the middle row of pics they're going to pins 1,2,3


The red wire I have going into pin 1 will be connected to the 47 ohm resistor and the green wire is going into pin 2 will be connected to the 150 ohm resistor. The black wire I have going into pin 3 will be connected to ground. And the hard part is done.

Step 15: Insert grey connector back into bottom of steering column and zip tie the wires you just put in to the existing harness.

Step 16: On the PAC adapter harness take the black wire and connect it to ground. Then connect the red wire to ACC 12v. I just tapped it into the stereo harness ACC 12v line. Which happens to be red also.

Step 16 plug PAC harness into PAC adapter. Then plug the remote wire (it looks like a headphone jack) into the OE remote input on your headunit and secure the adapter in somehow. I just stuck mine on the metal bracket.


Step 17: Program the version number. Our trucks are version 3. Follow the directions on how to set it.

Step 18: Program the buttons. There is a sequence chart in the PAC directions that you have to follow depending on which brand radio you have. Since I was installing a pioneer there is no option for power. So I just set the power button as mute.

Step 19: Put your dash back together and enjoy not having to lift your hands off of the wheel to perform basic functions. On a side note. decide before hand what functions you are going to program and which you're going to skip. When I first did this mod the preset up/down came before track up down and the adapter wont do both it just takes the first one input while programming. I prefer track up/down personally but it's up to you.

OK, thread complete. There are a few steps I didn't have pics of but they are pretty simple. My wife was my photographer and she wasn't there for every step. I hope this helps some people out. I know there are a lot of threads talking about it. A lot of people think it's pretty difficult but as you can see it's only three wires. It takes all of 30 minutes to do so if you've been wanting them, give it a try.

05cc4x4 you've inspired me to give it a shot. I was thinking about getting the wired control for my AVIC-D1 but this is alot better. Gives it a factory look. Parts are on the way. Thanks for your awesome write up.

Just completed this mod this weekend. I would highly recommend doing it. It is so much nicer to have the stereo controls on the wheel.

I called Courtesy and the guy I talked to was of no help. He said you can't do it. Part # 25550NA was no help either to him or to me using there online parts book. Help. I just got the truck, 2006 NISMO, and want to install a JVC KW-XG700.

Here's a link to the part's page: 251 Switch :: Body Electrical :: Genuine Nissan Parts :: Frontier (D40) 2005-2008 :: CourtesyParts.com

As for can't do it. He is obviously wrong due to the ingenuity of the member's here. The part number though is for a 05 only. You can wait to get the pin mapping from rboyd1780 for he did it on his 08 which he said he used the 05 part number. Or you can get the right one for your 06 and try. The author of this sticky I believe would help you out if you have any questions too.

Thanks iefronty, I used your link and ordered it without the so helpful sales rep. I went to Crutchfield for the JVC, the PAC, harness, and trim ring. Speakers will be Infinity 2way Kappas, eBay items.

A little off topic but...

What are the chances that the Cruise control switches will work on a truck that did not come with cruise control, and or would anyone who has done this swap be interested in selling their old cruise control panel?

Is this thread no longer needed? It was so hard to find I thought it had been deleted. If so I want to clean out my photobucket and delete some pictures. If you guys still want the how-to let me know and I wont delete them.
Thanks, Justin

Justin, that is awesome. Great work. I'm not that adventurous when it comes to modin my truck.
Next time you are in the Madison, MS area, let me know. I'll get the parts and let you rework my steering wheel.

I'll take that as a no to deleting the pictures. I was just looking to use my photobucket a private family site to exchange pics with relatives now that I live on the west coast. I'll look around at some other sites. As for helping you're out of luck. I just moved from Florida to Washington state. I could only get farther away if I moved to Alaska. I would say just give it a try. The 2008's spiral cable (the one between the steering column and the steering wheel) is wired different. There was a guy that read his out with a multimeter but he never posted back up with the pin to pin info. Granted I've done it on 3 vehicles now but the last two it only took me 30 minutes to install and wire them. If your not a 2008 then you should be able to use this thread no problem.

Please don't delete them! I am going to try it... What would need to be changed for an 08?
The pins in the connector behind the airbag go to different pins on the connector on the bottom of the steering column. Someone on the board read them out with a multimeter and got it to work but never bothered to post them up to help out everyone else. I would do it but I don't have an 08. It's not hard it only takes like 5 minutes to read them out. Also you have to buy the part for a 2008 so my part number is wrong for you. You just have to get one for an 08.
