Steering Wheel Wiring Question

Ok all you electrical and internet search gurus. I'm attempting to wire a 2014 Maxima steering wheel into the X. I looked and can't find the wiring diagrams for the connector behind the air bag on either vehicle. So far I've switched the Red, Black, and Green wires around to match the positioning on the Xterra plug. This has gotten it so that cruise can be turned on but not set and the horn doesn't work yet either.

The horn should be mechanical. There should be contacts that complete these horn circuit when the airbag is pushed in.

Can you take some pictures of what you're working with so I can get a better grasp on the situation.

Ok, I'm gonna ask a potentially stupid question here, but...

Why? What does that wheel do that an xterra wheel doesn't?

It's a leather wheel that has built in radio controls unlike my vinyl wheel that only has cruise. To top it off I got it for 1/3 of what I could have gotten an X wheel on ebay.

Jay pics will be up in a few.

Plug for column on the X wheel. Green wire plugs onto the back of the airbag assembly.

Current setup for maxima wheel. Green wire is seated in as best as I can tell.

Grey plug after I switched the Red/Black/Green wires to match the X plug. Allowing cruise to at least turn on but not set.

Grey plug on maxima before I did anything to it.

Are you trying to use the Xterra clock spring? Or the maxima one?

You'll really need the wiring diagram for both cars in order to make sense of it.

Do the airbag plugs match up?

The two big round things on either side at the top should have Springs underneath them. Those are your horn contacts. There should be a single wire spade that connects to the back bracket so that when pushed the airbag will complete the horn circuit.

This is exactly why I ask you guys cause I got no clue what a clock spring is. I took the airbag and wheel off of the X and then put the maxima ones on, didn't swap any parts between the two. I looked for wiring diagrams but can't find anything that shows the wiring for the gray plug at the top of the steering column. Yes the airbag plugs match up just fine. The white "box" with the green wire plugged into it connects to the red & black wires you can see in the background they run to the bottom of the metal bracket and look like they attach there but I lose sight of them.

The clock spring is the spool of wire that spins with the steering wheel at the base. It's where that gray plug goes. Behind the actual wheel. A clock spring that has stereo wiring is going to be a lot more complex than one that only has cruise control wiring. I'd start by seeing if you can get a maxima clock spring that has all of the in wheel wiring. Maybe swing by a stealership and see if they will xerox the schematics from the two FSMs for you. The should have full wiring guides.

I've got 6 of the 8 wires on the 14 Maxima wheel mapped out - Cruise, Radio, BT and Horn. Are there any other switches on there?

***UPDATE***

One issue solved horn works now, I went back out to take more pics for Jay and realized I had overlooked the clip on the back of the airbag.

So now the issue is just needing the wiring diagrams so I can figure out what needs to go where on that grey plug.

This^^ your steering column isn't likely preconfigured to accept those controls, you're going to have to wire that stuff too.

Also, the colors in the wiring diagrams don't match up with what you're showing. You're certain it's a 14 wheel?

Ah ok in that case I'm using the one from the X.

I've got a Axxcess ASWC-1 radio controller I'm gonna attempt to wire in once I get this all figured out.

Also, the colors in the wiring diagrams don't match up with what you're showing. You're certain it's a 14 wheel?

The colors or the positions because if its positions I've swapped some of them to mirror the one from the X wheel. I was told it was a 14 by Pro-2X which is who I bought it from.

Don't wanna tell you the wrong thing so here is a picture.

The positions. There's also a pink and red I can't account for. Yet. The colors I've figured out are:

(Maxima)
?? ?? Green Brown Black Blue White Yellow

Yeah that's the picture of the plug just how I received it, thanks for trying to figure this crap out. I hate wiring as I've stated many times before.

If you have an ohm meter, you could help me figure a few things out...

Place the black probe on the brown wire, and the red on white. Then, press the <source> button on the wheel. The meter should go (near) to 0 ohm
Place the black probe on the brown wire, and the red on blue. Press the <Volume Down> button on the wheel. The meter should go to 0.
Now do Yellow and Black and press the Cruise On. Again, it should go near 0.

If you can do this and let me know the outcome, that'd be wonderful.

Sorry don't have an ohm meter, and yes i know I'm violating the first rule of wiring and electricity.

this thread might be of some use to you. http://www.thenewx.org/forum/showthread.php?t=30646

Not sure about the colors on the maxima harness, but you might be able to go from just this and figure it out. If not I would try and find a diy for adding the steering controls to a maxima, and cross reference with this thread and you should be able to find out what all the relevant wires are for each and hopefully figure it out from there.

And from what I have read the wiring harness and the clockspring on the xterra are the same with or without factory controls, its just that not all of the wires a connected to, or maybe even make it as far as the harness on the radio.

Well, crap. When I get back home ill let you know what the wiring maybe should be to hopefully work. In the mean time, GO GET A FRIGGIN DVOM!!

I'll give it shot it's better then me playing plug & play. I'm not going anywhere we are getting a light dusting of snow/ice and the idiots are out in abundance, they are more likely to wreck me then the snow is.

OK. Let's try this. Going from left to right, as in the picture:
Green
<empty>
Yellow
Black
Brown
Blue
White
<empty>

The only issue I can see right now is the 2005 X radio controls are one way and the Maxima are different. Since you're using an after market head with a steering wheel adapter, you should be OK.

Leave the red and pink unplugged for now and test EVERYTHING. If it works, tape them up and be done with it.

I'm gonna come back out tonight and see if that allows for the controls to illuminate.

So I will have to get an ohm meter when I go to write the steering wheels controls so I can figure which wire is which.

I did learn an interesting fact that caused this whole confusion my X will not set cruise control until almost 30mph. I thought most engaged at 20 so I hadn't gotten out on a main road to test it I had been on my curvy a$$ back road. So I apologize for all the work you guys did trying to figure this out when I had it wired correctly (minus the horn).

Dah, Illumination!!! That's what the other two wires on the Maxima wheel are. Don't worry about those two wires since the 2005 X doesn't have provision for steering wheel illumination. Having black and brown flipped shouldn't be an issue, as they are both ground wires for their circuits.

Problem is the spiral cable doesn't have the provision for it. It's an 8 pin connector on it, but there's only 7 populated.

The fun part is gonna be playing with the meter so I can figure out the radio controls. That probably wont happen till after this weekend though since I've got Guard.

.....I'm tellin ya. You may get the wires for the wheel in the right places, but, if there are no wires back down the steering column for anything that you didn't already have, you're in for a hell of a surprise...

Start making sure that the other side (xterra side) has the stuff in place to handle the extra connectivity before you beat your head on the wall too hard...

I've already got the aftermarket kit that is used to wire it up.

Hyde's concern is that the factory harness between the spiral cable and the factory radio termination may not have the proper copper in it. They've been known to leave out certain wires to save costs.

To run from factory harness to aftermarket stereo, correct?

My point I'm getting at is, confirm there *is* a factory harness...

I'm just gonna run the wires on the kit to the plug on the coil spring (thanks Jay now I know what it is).

Thank you, you see what I'm getting at.

It's an 8 wire connector that had 3 or 4 wires originally, you may only have 3 or 4 from the spiral cable to where that aftermarket kit is going to hook in, thus making it a lot of headache for nothing.

You need to know before you put a ton of work in, that there are all 8 wires running from the xterra side of the plug to where the aftermarket part hooks up, otherwise you need the wiring harness part off of an X that DID have all of those controls. Oh, and, just a quick note, that wheel is going to have functions that're extra screwy, cause, xterras don't have a separate volume for the phone/bluetooth.

I'm already planning on it not having the wiring so I was just gonna make my own going to the coil spring. Not even worried about the phone/bluetooth I just wanted the leather wheel and the radio controls were an added bonus.

....uh...does that aftermarket kit have that much extra loom on both sides? The ones I've seen always were a plug on one side and wires on the other...

No it doesn't it's only got about six inches. So I'm gonna go get so wire(not sure of the small a$$ gauge) and some butt connectors so I can connect it in. Then run the extra wiring up through the column into the back of the plug on the coil spring. That way once I've figured out which wires go into the opposite plug on the airbag side I can just plug and play.
