Canadian DRLs

Update with pictures

Sorry for the lack of progress with this project. I have received the H11 connectors but not the fuse holders. So I have decided to assembly the circuit instead of keep on waiting for everything to arrive. The portion of the circuit in the box on the schematic diagram is what is soldered onto the prototype board.

Here is the top view of the circuit assembled:

Here is the bottom view. The black marks on the board is where wires will go for the harness. The 2 arrows indicate where the trace was cut because they should not be connected.

I will have to do some measurements to see how long to cut the wires for the harness. Hopefully I will have some time tomorrow to make the harness.
 
I started to assembly the harness today but ran into some problems with the wiring. I only have the wiring diagram that do not have the DRL circuit and according to that diagram the lo-beam via the connector gets power from the relay, then to the halogen light and then goes directly to ground.

The DRL circuit can be wired 2 ways:

+12V --> DRL module --> lo-beam halogen light --> ground
or
+12V --> lo-beam halogen light --> DRL module --> ground

I have to determined which way the M5 is wired because this will affect how the MOSFETs are wired. I found the polarity of the factory lo-beam connector when I was doing my HID conversion but did not measure to find out if the negative part was going directly to ground.

Finished work too late tonight to do any measurements because I do not have a garage and cannot do this on the street in the dark. Also the wife does not like it when I fiddle with the car so I have to do this when she is not around.
 
H7 connector polarity

I managed to check the wiring of the H7 connector before I left for work today. I also found that the colors on the wires does not match up to what is stated in the factory wiring diagram. Here is the way the DRL circuit on my 2006 Canadian Mazda 5 is wired:

+12V --> DRL module --> lo-beam H7 halogen light --> ground

The polarity of the H7 female connectors is as followed:

I worked on the harness today. I was rushing and ended up making some wiring mistakes. After a couple of hours I finished and tested the Fog light portion of the circuit. I ran out of large gauge crimped 1/4" female spade connectors. I will see if Canadian Tire or The Source have them, if not I will go to our local surplus place in the weekend.

In the meantime I can finish wiring and test the rest of the harness and just put the spade connectors on later. The end is near.
 
I think you will make a lot of cash selling those harness, if it's almost plug and play, a lot of us will buy you this harness me first !

Thanks a lot for your great work Dave !
 
Prototype almost done.

The harness and circuit is 90% complete. It has been tested on the bench and it work as it should.

DRL on --> fog lights on, lo-beams off
Lo-beams on --> fog lights off
Lo-beams on, fog lights on

The only item left is to put a heat shrink over the controller board and determine the polarity of the factory H11 fog light connector because the H11 connector I have is polarized and can only fit in one way. I will see if I can replace this with 2 1/8" male crimp connectors.

Here are the revised schematics for stock configuration (Halogen fog and lo-beam), H7 (lo-beam) HID conversion with relay harness, and H7 with H11 (lo-beam and fog) HID conversion with relay harnesses. The same controller circuit can be use for all 3 configurations, the only difference is the use of relay(s) and extra wires.

Here is the almost completed harness for H7 HID conversion that have a relay harness. The only thing missing is the heat shrink over the controller board and the connectors to go to the factory H11 connector.

The last step is to actually tested on the car. This will have to wait until the weekend.
 
Wow, i'm speechless ! hehe Great work Dave, How much (approx) does it cost you to do that ?
 
Have been busy at work the past few days. I will have a parts list with prices tomorrow. I am trying to source all the parts from 1 or 2 suppliers and will substitute the 3 H11 sockets ($15CAN) with 6 1/8" crimp quick disconnects ($2CAN) used in the fog light portion of the harness to keep the cost down.
 
Here is the parts list and their prices. There is a column for "Stock Halogen" which is the factory setup. Another one is for someone that has already done the H7 HID conversion using a relay harness, it will also work for someone that has done a H11 HID conversion and did not use a relay harness.

I source the parts from 2 places:

http://www.digikey.ca

http://www.addison-electronique.com/

To sum it up if you have a stock system it will cost $40.66 and if you already have done a H7 (with H7 relay harness) and or H11 (without H11 relay harness) conversion the cost just for parts are $29.17.

If I were to make the harness, there is also the labor cost, I estimate that it will take me 1.5 to 2 hours to build and test a harness, and there is also the shipping cost. I will have to draw the wiring diagram and make sure the parts list is correct to finalist the list.

How much for a complete set like this with labor ?

- H7 HID with relay and H11 with HID (no relay)

I will go take it since you are in MTL i will save on shipping and see how it install !
 
I'll take one too. Just let me know when/if you will be making these available to buy.

I have been trying to document this if anyone wants to build this themselves. As I was drawing up the wiring diagram I realized that I can make some changes to make installation a little easier. I will also be updating the original parts list to reflect the changes, the new parts are 3/8", 3/4" black and 3/8" red wire looms to protect the wires.

Now to the disclaimer, this to me is considered an experiment mod and people who decide to do this mod is doing it at their own risk. I am not responsible for any damages to your car if you try duplicate what I am doing and install this into your car.

It may be easy for me to do this mod but I need to know how difficult it is for others who is also trying to do this. So, I would feel much more comfortable if Montreal area members try this first, this way I can provide assistance and advise before making a kit available to the rest of the members. This way, if there are any issues such as installation procedure or changes to the circuit they can resolved locally.

I can make up another harness by this weekend and can help a local member in the installation of it if there are any takers. I will provide some installation instructions for him or her to follow and will be present during the installation to provide assistance if required. Does this sound reasonable approach? Any input and advise is welcome.
