DIY: JDM Fog Light w/ OEM Switch
Disclaimer: Installation was completed on a 2013 Lexus GS350 F-Sport. This tutorial could be used as a reference against other models. It's always recommended to verify all connections via wire diagram.
Extra Parts Needed
Part# 93567-A5014 (Fog Light Screws) x 4
Part# 82998-12870 (N28 Connector Pins) x 2
Part# 82998-24350 (BA2 Connector Pins) x 2
Relay/Fuse Connections
BA2 Connector - Pin 39 (Left +)
BA2 Connector - Pin 40 (Right +)
Fog Light Switch Connections
Ground
N28 Connector - Pin 10 -> N28 Connector - Pin 19
On/Off Function
N28 Connect - Pin 11 -> N12 Connector - Pin 27
Spot relay fuse box
You will notice an integration relay unit and wire harness
This will be the main wiring harness that you will be tapping into
Two white wires have been added to power the fog lights. I combined both wires together and connected it to the positive side of the relay harness.
This will be a similiar relay harness provided in your kit. The red circle indicates the part in which I cut off. You will be left with a postive and negative wire going to the left and right plug.
Running wire from driver side to passenger side (provided by member 4matador)
BA2 Connector (Relay/Fuse)
N28 Connector (Fog Light Switch)
Area to access main body ecu (red circle/behind coin tray)
N12 Connector (Main Body ECU or Multiplex Network Body ECU)
I did not bother to purchase a pin for the N12 connector. I ended up pushing in the wire I extended from the foglight switch and zip tieing it down.

Good work!
Did you remove the steering wheel to install the OEM stalk?

Awesome DIY! Thank you PK_Celsior for taking the time to write & document this entire process.
I don't have a need for this, but I am sure this will help MANY to come.

So the positive side of the foglight harness you connect to BA2 pins 39 &40 and with the ground side of the harness you connect it to N28 pins 10 &19?
On N12 pin 27 you connect a separate single wire to N28 pin 11 right?
