For those that are considering a window roll-up module, here is some helpful information on which wires to look for. This module has been installed on many other Nissan's, but I have not seen anyone tackle this on the QX/FX, so finding the wires can be a chore!
I've never been able to figure out why on so many vehicles in the US allow the ability to lower the windows using your keyfob but not raise them. A lot of folks already know that you can roll down your windows if you hold the unlock button. On those hot summer days, I like to crack the windows open using the keyfob and then if the rain comes in it is a pain to outside, put the car in acc mode, and roll them up.
I did a lot of research and ended up purchasing a roll-up module from KP technologies. I tried several others and they were more hassle then they are worth.
Here is a link to the one I got. KP Technologies
A couple notes why I chose this one in particular. This module activates clicking the lock button twice using the keyfob. Some others close the windows on one click or on three.
I preferred the option to close the windows on two clicks of the fob because after one click my mirrors auto fold- For a review and how-to-install that see: QX70 09-17 - How-to-install auto mirror folding module
On three clicks my remote starter actives. For a write up on that see: HOW-TO - How to Install Fortin Remote Start
Two clicks was ideal for me...
The KP module simulates the same functionality as if you were to put the key into the driver lock and hold it in the lock position, it will roll up the windows that have the auto roll up functionality, in the FX that is the front driver and passenger window (unsure why Nissan did not enable auto roll down and auto roll up for all 4 windows, but this what we have).

The Install...
Install Time: Took me 4-5 hours mostly because I was searching around for all of the necessary wires but if I had to do it again, I could do it in 1-2 hours max. The only thing required to install this is the connection of 4 wires, finding the wires is the tricky part, but with this tutorial, you should be able to in no time!
Cost: $80 with shipping- This is a little on the high side but for the seamless functionality it was worth it, I tried other brands and did not have good luck.
Parts Needed:
1. I like to use pry tools to avoid damaging the upholstery. You can find these below on amazon, search for auto pry tools.

2. Remove the driver door panel

3. Disconnect the harnesses from the door panel
Once you have the door panel removed. A few important things to remember.

4. Find the wires required.
5. Connect the wires. In the main window switch wiring harness connect the following three wires pictured in the second picture following below.


I mounted the actual module right under the window motor, it fit in there pretty snug. Run the blue wire that connects behind the speaker through one of the grommets, you can make a little hole in it.

Then reassemble everything back together,
Important note:
You have to program the auto rollup windows again after reconnecting the window switch to the harness.
This is done by holding the switch to roll up your windows all the way up and then holding the switch for a few seconds after the window is closed.
This needs to be done for both the driver and passenger windows. Until this is done this module will not work because it uses the auto up functionality.
Any questions feel free to ask, hope this helps those that are considering this mod.

Cost: $80 with shipping- This is a little on the high side but for the seamless functionality it was worth it, I tried other brands and did not have good luck.
Parts Needed:
- Pry tools (but you can get away without having them)
- Soldering iron or wiretaps
- Solder, flux
- Electrical tape
- 10mm socket
1. I like to use pry tools to avoid damaging the upholstery. You can find these below on amazon, search for auto pry tools.

2. Remove the driver door panel
- Prying the door handle off
- Prying the plastic cover behind the door open latch and lock.
- unscrew three 10mm screws using a socket (two in the door handle and one behind the door latch all circled below.
- Remove the light on the bottom of the door by prying it out and disconnecting the harness.
- Gently pry up the door panel on both sides and bottom and then lift up, it slides up from the window area after unlatching it from the door on the sides and bottom.

3. Disconnect the harnesses from the door panel
Once you have the door panel removed. A few important things to remember.
- Disconnect the harnesses outlined below.
- The fasteners (circled below) that hold the door panel to the door have little felt washers on them, make sure that you keep the felt washers and reinstall them if they fall off, these keep the door from creaking, had to figure this out the hard way! Any fasteners that came off or got stuck in the door after removing the door panel should be removed and reinstalled on the door panel prior to reassembly.

4. Find the wires required.
- Three of the 4 wires required are going to be in the main window switch harness that is outlined in the red rectangle below, one wire is going to be in a harness behind the speaker. The speaker needs to be removed, three 10mm bolts.
5. Connect the wires. In the main window switch wiring harness connect the following three wires pictured in the second picture following below.
- Module Yellow- Red in-vehicle
- Module Green- Purple in-vehicle
- Module Yellow- Orange in-vehicle
- Module blue- light green in-vehicle behind the speaker. Third picture below
