Touring Seat Installation Help - No power or Heat!
 

So, I swapped my base cloth seats for leather touring seats a few months ago. The wiring for the touring seats was in place under the seat, but no power was coming out of the positive wire connectors. I tried adding the "heated seat" relay under the hood and adding a fuse for every empty slot in the fuse box hoping that would help, but no dice. Therefore I ended up adding a power wire from the battery to each of the seats temporarily until I had more time to work on it.

Also, I purchased the OEM heated seat switches, but when I pull up the center console and cup areas to install the heated seat switches, there is no wiring for these switches! I pulled back the carpeting as well to see if they were hiding, but no luck. :(

Does anyone have any advice or experience with this installation? I've checked on courtsey nissan's website to see if their is a wiring harness I'm missing, but I don't see anything?

THANK YOU!

Do you have a copy of the FSM? it should have a wiring diagram which would prove invaluable.

Sub'd because my wife will be getting my touring seats when my new ones show up. I was wondering about these things...

remove the cupholder and see if the harness is there or under the seat...

yup, I've got the service manual... still haven't been able to track down the wiring pieces I'm missing. Here is what I have found thus far, it's listed as a console sub harness, but it looks like its for the ipod plug, not the heated seat switch:

How about finding a wrecked one??

Any news/update on this?

That sub-harness is connected to the inside key antenna (and, it appears, the iPod jack, but I'm not sure). It may also be connected to other stuff in the console - I didn't dig too deep.
There is also a FSM section on seats (SE), but I didn't see anything useful on a Q&D look.

My _guess_ is that you are missing at least one harness (from what I have read, Nissan doesn't include the rear fog lamp harness if the lamp is not installed) and possibly the seat heater relay (behind the center dash).

If you need help interpreting the wiring diagrams, I may be able to give you some hints.

So when I pull the seats out of my car to put in my wifes:

Can I pull out all of the harness I need for everything to work?

If I do will it effect anything else in my car in a negative way?

Thanks I will dish out some rep for answers!

You should be able to remove any harnesses between the console and seats, except for the one(s) going to the seat belt buckle switches, air bags, and passenger weight sensor. Ie, unless you want the dash to light up, you will need most, if not all, of the harnesses. I will try to check the wiring diagrams later today to verify (if you don't hear back by ~10PM Central US, poke me).

Thanks man!

Well, my big chore for today was cancelled, so I did some digging through the FSMs. Here's what I found:
Referencing 2009 FSM SE-5, SE-8, SE-11, SE-23, SBC-10, SBC-16, and SRC-157, I see nothing that will affect vehicle operation (other than warning lights) if the seat connectors are unplugged.

A visual inspection of my 2009 Touring (includes electric seat warmers) indicates that there is just one, "medium-sized" harness running from the console to each seat. These harnesses branch off under the seats to go to seat position/recline switch and such.

My conclusion is that you can remove the console/seat harnesses, assuming the connectors in the console don't contain pins with other circuits (I can research that, but it's a PITA), but you will trip seatbelt, SRS, and maybe other alarms. If all else fails, there may be enough room in the console to allow you to tuck the harnesses in there.

Disclaimer: I'm not an expert - check the FSMs or a qualified technician before performing any modifications.

Im so confused. So im going to get a bunch of lights when I put in my aftermarket seats? I hope there is some kind of bypass plug I can use.

My 2012 was prewired, to see if you have the wiring you can pop the cup holder and you will see 2 plugs for the heated switch wiring and under the seat if u look there is an extra plug not being use. If you have these then the car is pre wired. The only thing I didn't confirm was if the relay was actually there but since there is power going to the seats, should be working.....

I told OP that posted this, he will just need to use a relay and wire it straight to battery....

If you can mount the seat belt buckle assemblies to the new seats, that should take care of that warning. Somewhere on this site, there is a DIY explaining how to use resistors to get around the air bag warning. There is also a DIY on removing the passenger weight sensor and installing it in a new seat - requires upholstery work, so that's out of my league - but I can't remember if it is on this site.

So I guess the question is, where is this harness going from the seats to the console hidden in a non-touring model? The wiring harness is there under the seat, but I don't know where it's hidden (in the dash or somewhere beneath the carpet). And, does this hidden harness have the heated seat wiring connectors for the switches?

My harness is attached to the seat frame and then goes under the carpet. I didn't pull up the carpet to check the harness routing, but, according to the FSMs, the connector on the other end of the harness is in the center console. I could not swear that the harness doesn't physically go to the door sill first. I'm assuming that they took they shortest possible route and the harness passes either in front of or behind the seat rails and then heads straight for the console.

It would take more digging than I have time for right now to verify this, but I believe the heater switches have their own connector with power in and outputs to heating pads. You can look at the SE FSM under the System Wiring and Terminal Layout sections to get a better idea of how the switches/heaters are wired. Seatbelt and airbag info are in the SBC and SRC sections, respectively.

Edit: Keep in mind that I am only going by what I read in the FSMs. I've never attempted a project like this nor am I 100% sure that I am interpreting the FSMs properly. I'm just trying to give you some hints until someone that knows what they are talking about shows up.

THanks for the advice. I will probably pull my pasenger's side seat out again and see if I can track it down the harness through the carpeting. If you happen to look into where the heater switch wiring harness runs, I would appreciate it.

Please do let us know what you find. I don't plan on cracking open my console anytime soon, but, if I do, I will let you know what I find.

hate to pull a thread back from the dead. I am wondering if anyone figured out what is missing on the 2010 models to make it work properly? I bought some heated/power seats and just like delorean I found the wires underneath my base model seats taped up. After hooking up the seats I found no power was going to them. I also checked my cupholder when installing the heated seat switches but no plugs were found.
So now I sit with seats leaned all the way forward that cant adjust due to no power going to them. Im going to run a wire from the battery as a temp fix to hopefully get them to move. Would love to get them to plug in properly and get the heated seat function to work.

you are probably missing the relay or fuse, my 2012 had it. Take a volt meter to your harness under the seat, I have a thread showing u how I had power etc. That's the first thing u need to check. If the harness is there, most likely power is there for the power seats. Could be ur missing the fuse only.. so look at that first. Then worry about the heated seats.

yeah ill try to grab a guide and look. Im going by what delorean said about installing all the missing fuses and it not working. Some good news is I did tap into where the power should be coming from on the seats and did a direct connect to the battery to see if it would solve the problem. It did allow me to move the seats. so worst case I will just run power to the seats that way.

did you ever figure this out becauseI'm pretty much having this exact predicament, tried 2 dealerships and it was devastating how useless they were...

I have the touring, but my car is in storage, so I cannot help.
Ask around in the Audio section. Most of those guys have gutted the interior to install deadening material.

OK guys,
I have looked everywhere and am stumped. I have a 2009 Sport and have purchased the touring seats here locally. I do not have the heated seat switches under the cup holder and appear to be missing part of the harness under the seats that power the power seat function. I am pretty sure the 2009-2010 models did not come with the whole wiring harness or at least that is what I have read.

My question of course is what harness am I missing? I have been trying to solve this for the last couple of weeks and so far this thread has given me the most info but not quite enough to find and order the correct harness. Please, if anyone can help me I would be very, very grateful and throw some rep points at you. Thanks in advance.

If nobody comes up with a good answer, try contacting some place like Courtesy Parts.

Tried courtesy parts website and while it is indeed a great one I was unable to figure out what I need. The heated seats are not that important to me at this time (summer) and I can wait to tackle that project in the fall but I really need to be able to move the seats around.

Please, please, pretty please give me a shout if you can offer any type of info or advice. Thanks in advance.

Strange...my 2011 base/sport have all the harnesses ready to accept my touring seats. It was plug and play in my case...I wonder if Nissan left out those harness on the older models. I'll be working on the car tomorrow, I'll try to grab some pictures of the harness locations for you guys.

Thank you guys for your input, from what I have gathered and is by no means accurate but here goes:
2009-2010 models did not come with the additional wiring harness and plugs so we are a long ways from "plug and play". Also, as far as I can tell the 2011 and later models had the wiring in place so you guys had it easy��������.

Where I need the help is I am sure there is a wiring harness that I am missing and so far unable to locate, this ( I think) would be a harness to include the heated seat relay behind th cubby as well as thenheatednseat switches and let's not forget the power seat function.
I have not been able to locate this harness.

Please, please, please, help me.
Thanks,
Puke

Call them and talk to someone.

Do yours actually work? I have a 2011 base and just installed everything. Everything was plug and play, except the actual heated seats don't seem to work. Switches turn on and everything. Seat moves with the switches, just no heat.

Make sure a fuse is installed for the heater circuits.

Sweet man. Any idea which fuse box it's located in? If not its cool. I'll do some research.

Location is probably in the Owner's Manual. If not, FSM will tell you. You can download both, if needed, by following the link in my sig.

If fuse is located in the IPDM-E/R (next to battery in engine compartment), one of the "pull the steering lock fuse" DIYs will show you how to get to it.

IIRC, the power to the seat heaters goes through a relay that might not be present. Wiring diagrams, physical location of relay (if it exists), relay specs, etc will be in FSM.

Heated Seat relay is in the hood next to the driver headlight. Going to go see if any auto part store has one, tomorrow. Hoping it's as easy as that!
