Is there anyone on here that can help walk me thorugh the KP Tech Fog Light mod for a 2011 G37XS Sedan? I would like to find some pics since kevin has actually installed one on a 2010 or 11 Sedan. Which section of the FSM am I supposed to use for identifying the wires? Also any recommendations on best ways to sotter the connections?

 

The wiring diagram for the fog lights in on page 83 of section 'EXL' in the 2010 FSM (attached).

In my opinion, you might be better off using good quality crimp connectors instead of soldering and taping (or shrink tubing) any connections for the KP module, especially if you haven't had some experience with soldering and taping wires.

 

i wish they had one for the 07 sedans..;-(

 

KP Technologies Fog Light Control Module

E-mail Kevin at KP Technologies. I bet this module will work in your 07 sedan if you can figure out the wiring to install it correctly.

I''m not sure what mod you are interested in. The OP wants a fog light module. This gives you completely independent control your fog lights using the G's fog light switch. You can turn your fog lights on using the fog light switch regardless of whether your headlights or parking lights are on or off.

A DRL module (if wired to your foglights) would turn your fog lights on any time your ignition is on. The fog light switch would be disabled.

 

thats what i thought a fog light module is; have the ability to run DRLs by independently controlling it during th nighttime and daytime

 

Ok So I am beginning to try to figure this out. KP technologies offers the Fog Light Module MX 20 which supposedly has the waterproof relay supplied with it. There are five wires on fog light module - orange, yellow, black, green and blue. The directions from KP state to mount the Fog light module inside the car next to the body control module by the dead pedal. The orange wire is supposed to go through fire wall which will be connected to the supplied waterproof relay.

1. YELLOW – 12VDC IGNITION POWER (Light Green @ BCM)
a. Connect this wire to a source at the BCM that reads 12 volts only when the ignition switch is in the ‘ON’ position.

2. BLACK – GROUND (Black @ BCM)
a. Connect this wire to a constant ground which is WHAT WIRE? the black wire coming from BCM?

3. BLUE – BCM OUTPUT (Gray @ BCM)
a. Connect this wire to the matrix output corresponding with the function
you want to control (ie fog lights). So connect the fog light mdule blue wire to the BCM Gray wire?b. This wire contains a digital communication signal and can only be verified
with an oscilloscope. It is highly recommended to reference your vehicles
specific service manual to insure proper harness and wire identification.

The other part of the directions include cutting and placing the wires into the Pins. Does anyone have recommendations on how to get the wires into the pins of the relay switch and IPDM?

 

By looking at the pin-out diagram for the BCM (attached) and the wiring diagram for the fog lights I previously posted, it looks like you can use either pin 6 or pin 13 (both are black wires) for "BLACK – GROUND" wire from the module.

For the BLUE – BCM OUTPUT wire from the module, it looks like you are going to use either pin 90 (P=pink wire) or pin 91 (L=blue wire) to pick up the BCM data signal for the fog lights. I would try one of these two pins first and see if it works, and if not then try the other.

I'm not sure what the best way to cut and place the wires into the pins would be, maybe someone else here could help you with this.

 

Thanks. I emailed Kevin as well to get his input and this is what he said.
The KPtechnologies supplied relay should have a wiring harness attached to it. This wire harness can be spliced in to the KPtechnologies wiring and the vehicle wiring. All of the connections to the vehicle should be made “mid wire”. Strip off 3/8” of insulation, wrap the KPtechnologies wire around the exposed copper, and solder. No
connections should be made within 2” of a harness to make sure there is enough wire left to work with if something should go wrong (like accidentally breaking the wire).

When installing this module I recommend to start by connecting the yellow, black, green and blue wires on the KPtechnologies main control unit to the vehicle. If you get these four wires connected properly the module can be tested. There is a small LED mounted on the circuit board that can be viewed through the opening where the wires come out of the module (no need to take the box apart). When the fog light switch is “ON” the LED will be “OFF”. With the switch “OFF” the LED will be “ON”. The LED is reversed due to the fact that you have a sedan and the OEM hardware is reversed on the sedan.

Once you get that part done, the next step is to connect the relays coil (Pin 85 and Pin 86). The relay has pin numbers printed on the bottom of the relay (it must be removed from the wire harness to view the numbers). With these two pins connected properly the relay should click on and off when the fog light switch is turned from “ON” to “OFF” and from “OFF” to “ON”.

Once this step is complete the final step is to wire the remaining three wires of the relay to the high current fog light wires.

From the IPDM each fog light has its own separate feed. However, inside the IPDM they are common (fed from the same relay). You will need to find both the drivers side and passenger side wires and cut them both. The side of each wire that goes to the fog lights will need to both be connected to Pin 30 of the relay. You should have two wires left from the two wires you cut – connect one of them to Pin 87 of the relay and insulate the other one as it is not needed. Pin 87A then needs to be connected to a switched power source through the fuse. The module should have came with about 10’ of thicker blue wire that can be used to connect to an ignition source inside the vehicle. I generally connect the KPtechnologies yellow wire to the thick ignition feed to the BCM, then connect the blue wire, through the supplied fuse, to the same source. Run the blue wire through the firewall to the under hood relay.

 

Is there anyway you and I can walk through the installation of this since I received the kit from Kevin and you have the wiring diagrams and knowledge?

 

Kevin knows lots more about this than I do. I think the best thing you can do is to e-mail Kevin the wiring diagram I posted and then confirm with him what I said about how you would wire the necessary connections for the module.

Once Kevin confims that information, I can try and give you any other help you may need. I've never installed this fog light module on a 2010 G37 myself, but I've done similar type of mods on other cars.

 

Based on the wiring diagram and KP's directions which wire or pin do I connect the yellow wire to?

 

It needs to connect to a postive 12 volt wire that is hot only when the ignition is on. I'm not sure but either the white wire (pin 1) on connector M118 or the red wire (pin 11) on connector M119 might work, but I would check them with a volt meter before making any connections. Perhaps Kevin has some more info that would be helpful.

 

Got this reply from Kevin - He actually lives in the same city as I do and I am asking him to help me install this.

"According to BCS-6 the fog light switch is on Output 4 and Input 5. This is the common position for the fog lights and I would not expect it to change for 2011. Referencing the BCM PDF you supplied that would make Output 4 a Sky Blue wire at Pin 2 of connector M33 and Input 5 a Yellow wire at Pin 13 of M33. These wires are typically pretty small compared to the other wires at the BCM.

I would connect the KPtechnologies Yellow ignition power wire to a violet wire at Pin 123 at connector M123 (ignition feedback). I would ground the module either to the chassis or to Black Pin 13 at connector M119 (ground).

At this point the module should power up and function on a limited basis. There is a super bright LED located just inside the module that is visible by looking in to the module through the opening in the plastic case for the wire harness. The internal LED should toggle with the OEM Fog Light Switch. In the case of your sedan the LED should be ON when the Fog Light switch is OFF and should turn OFF when the Fog Light switch is turned ON. If this doesn’t work then verify the module has power across yellow and black (should be 12vdc) and then recheck your data connection lines.

Once you have the LED switching on and off the second part of the installation is hooking up the supplied relay under the hood and wiring it in to the fog light circuit. Wire the relay and fog light wires as directed in the installation guide. The fog light wire colors from the IPDM are white and blue.

Please be aware that all this information was pulled out of documentation provided by Nissan and has not been verified. A volt meter can be used to verify most wires but special equipment is needed to verify the data lines (an oscilloscope). Our module was designed with high impedance inputs for the data lines that can’t pull much current at all from the signal being referenced so the likelihood of damaging anything is virtually non existent but it is still recommended to verify everything before making connections."
