Default The HOW!

So how did I do it? Well, I would like to say its plug and play and super easy, but uhmmm, its not….

I WOULD say the auto dim mirror is easy, just hop on eBay or use Google shopping and search out Gentex mirrors, they will have 20 different models for you to choose from depending on what you want it to do and installation varies from a simple 12v connection to much more depending on the model but none of them are all that difficult. If you go with the one I did it only requires 12V which is easy to find in the map lights just in front.

I guess the Auto Headlights aren’t too difficult if you have had any experience with Automotive Alarm systems or other vehicle add ons. It is in depth though and not for the faint of heart. I apologize I didn’t take any pictures of the install but all connections except for one are made to the wires connected to the light switch (Illumination Control Module).


The auto Headlight system itself is the DEI 545T.

You will need to understand the basic working and connections of relays and diodes. Assuming you have this, following the instructions that come with that module will get it done.


The connections that need to be made are:

The first thing you will need is a Positive 12V source. On the relay Control Module you will find 2 HEAVY gauge wires on the plug closest to the door. A Red wire and a Pink with Red Stripe. The Red is Constant 12V the Pink w/ Red is the Switched 12V

The ONLY Wire that is not at the Illumination Control Module is the wire used so the system knows when your Wipers are on. This Wire is at the Body Control Module, accessible from the very top. Fairly high Gauge DARK GREEN Wire...



For the Headlights Relay, you can use Either the Yellow, or the Yellow Black wire. You will be using a 30Amp supply so it will handle both across the one wire without issue. If you do not like the idea of having both headlights on one Fuse then yes you could connect them both separately divided by 2 separate fuses.

For me, since my Fog lights are always on, and since the High beams will still work and since I could reach over and turn the factory switch, I wasn’t too worried about going back to 1 fuse instead of 2.





For the Parking Lights you will need to make 2 connections… YOU WILL NEED TO DIODE ISOLATE THESE if you wish to retain the function of the Left or Right ONLY side marker lights (the 2 functions on the switch if you turn it to the LEFT)
Gray / Red & Gray / Black






Interesting enough, even though the schematic only shows the FRONT parking lights on these connections, no additional connections will be required for the rear, again, unless you feel it necessary for fusing purposes.

You will need to make an additional connection for the License plate lights & interior lights however, and that will be any of the 3 shown, Gray or Gray / Violet or Gray / Yellow:





And last but not least, if you wish to have control of your HIGH Beams while on Auto Headlight Mode, you will need to run 12V to the Multi Function Switch. I suggest using ANOTHER 12V source rather than the same powering the headlights as you can see in the schematic that this isn’t just a sense circuit but WILL be supplying power to the High Beam Headlights. You will connect this to the White / Yellow wire.






DONE



The Fog lights aren’t difficult, but there isn’t an off the shelf answer here so I got creative and used a bit of Electronics Engineering.


So for starters, I hoped up on eBay and found me an extra set of switches….




Unfortunately you cant use the switch that’s behind the blank already in the car as it doesn’t have enough connections on it. You will need the switch that was used for the Electric Spoiler…


Then I found a company that does Plastic Engraving, supplied him with the picture I wanted done and sent the BLANK Plastic button front to them to have the Fog Light emblem engraved.

Contact was Jon Anderson, GREAT to work with!


While the cover was off being engraved, I took apart one of the switches. I noticed the bottom two connections were for illumination so I left those alone. I then modified the two switches (up and down) to output a momentary GROUND when pressed.

Sorry I don’t have more detail here but for those who know their way around a soldering iron you shouldn't have ANY problem figuring out how to make this modification once you get the switch open.

Once that is done, you then need to pick up a relay that will convert the output of that switch to latched 12V output. I chose a FRT3-SL2 Relay:

http://www.khalus.com.ua/data/chips/chameleon-relay/pdf/frt/frt3.pdf



(If anyone decides to do this and either the switch modification or this relay wiring becomes the stumbling block, send me the switch & 10 Bucks to cover the Relay, I will take care of it and take pictures on how it’s done this time to show others).


Keep in mind the above latching relay can NOT carry the current needed to run your fogs, so its output will be used to activate a larger (standard) automotive 30Amp Relay.


Once all of that comes together you are almost home free. A connection to one of your Parking lights (or better yet, the gray or gray/yellow wire for your interior lights) will be used as one of the triggers for your 30Amp relay (to ensure the Fogs can be on any time the Parking lights are on regardless of High or Low Beam status).

And the ground trigger will be supplied my the miniature latching relay.

For the actual 12V supply to the Relay, remember this should be strong enough to carry the 2 Fogs and for safety install a 15Amp fuse in line…

The 30Amp relay output will connect to the Fogs via the Gray / Yellow Wire from the Illumination Control Module.





So that’s it, Get you some switches, send the cover off to get the Fog Light emblem engraved, modify the switch to output momentary ground pulses, use the Mini latching relay to convert that to a constant output, connect it to a standard 30Amp relay and supply power to the fogs…


OK, whew! Thats a lot to try to put in a post! Not sure if anyone else will really want to go through this much trouble, but I am super excited about it and REALLY wanted to share!!!!
