Disclaimer: Use this DIY at your own risk, as I will not be responsible for any problems this DIY may cause.

This DIY will guide you through the installation of a KP Technologies MX20 Controller Module to run the fog lights independent of the headlights.

You will need a KP Technologies MX20 Controller Module (http://www.kptechnologies.com/products.php#/12) and your regular hand tools such as metric sockets set, wire cuter & striper, electrical tape, soldering iron and hear shrink tube if you chose to use them to complete this DIY. It will take approximately 2 - 3 hours at leisure pace.

1. Remove trimmings in the driver foot well to gain access to the BCM. The following pictures show the BCM location.

2. There are 3 connectors located on the BCM. The one we need to tab into is the biggest connector, M3 (40 pin connector). Disconnect the M3 connector and make 3 connections at the connector wires.

3. Ground the KP module black wire to nearby bare metal.

4. Route the KP module orange wire through the firewall to the battery compartment in the engine bay.

5. Reinstall the trimmings.

6. Remove the battery compartment cover and the cowl top cover.

7. Remove the battery from the compartment.

8. Remove the IPDM cover by pulling it straight up.

9. The E8 & E5 connectors are the ones you will be making connections.

10. Reach to the back top edge of the IPDM and unclip two tabs to release the IPDM from its mounting bracket to create some slack in the wires.

11. You will be cutting 2 wires and making 3 connections at the IPDM. Using the provided relay that comes with the KP module, make the following connections.
Note: The wire color of your relay pigtail may have different color. Just follow the pin # to make the connections.

Disconnect the E8 connector and wire the relay pigtail as in the picture. Reconnect the E8 connector when completed the wiring.

Handy_Andy for president? That's who I'm voting for tomorrow.

Thanks for continuing to provide detailed DIY's to :iS:!
 
Awesome write-up. Much clearer than the other. I was going to wire a seperate switch and relay, but now I'm more confident to to use this module. Thanx Andy.
 
The MX20 is a universal module. It's a matter of the wiring. I took a quick glance at 2nd gen's wiring. It should work too.
 
a few comments lol

1) Great writeup!
2) I'm confused as to how you even did this lol. I thought you had the custom bumper on your FX (ie no fogs)?
 
Thanks for all the good words guys. I was a bit confuse myself trying to follow the write up on the other forum. So I decided to write one myself. Hopefully, this will be easier to follow.
 
Once again, thank you Andy for this write-up. I was successful in wiring the module using your instructions.
