Tackling Factory Controls or: How I learned to stop worrying and love

[odave]

I had a couple issues, I got my bezel w/switches off ebay and the pass switch did not work, My first power board from amazon had 1 channel ng. But after I got a new switch from gmparts-now and a new power board from a different vendor on amazon. It was all good. So cool to have heated seats this winter!!!

Okay guys, sorry for the late responses and thanks to everyone messaging me on here and on YouTube.  If you could post your questions here so that when I answer the everyone has access to them that would be beneficial for all and now that I have had my last surgery I will try and be on the forums more often.  Also don't forget to subscribe to my YouTube channel if you haven't already as I have some more projects in the works that I will be sharing in the coming weeks.

Here is the logic for the Canny 7, this was created using the latest firmware, you will need to update to that version before loading this or the LIN communication will not work as the GM system uses a non-standard speed that I had the Canny people add to the firmware so we could use this device with GM systems.  That being said the original firmware that might be on the device may not support this but I have verified that it is available in the latest version.

Thanks and I look forward to any questions and by all means please report back like Dave!  Glad to see it is working out good for you!

thanks for all your help glad to hear your on the way of recovery i also got a defective power board and am waiting for another. to bad about the cab mounts but that is another story

another note do not use this program on 64 bit windows, you may get lucky but i had a problem with the canny 7 staying connected works fine on 32 bit windows

I think this is awesome and may be what I need. I have a 1956 chevy 3100 that I am putting power, heat and cooled seats from a 2018 silverado in. With this Lin system will I need to use this setup with the stock switches or can I go to an aftermarket set of switches that change the voltage supplied. I'm open to suggestions on how to get the heat/cooled seats to work.  

 

Thanks!!

Any thoughts?

Any thoughts? 

You will definitely need the Lin-bus system for this to work unfortunately

Nolan,

 

Sorry I haven't responded to your last message, been tied up.  If you are wanting to use the stock seats without having to use the factory modules you can use a device that will allow PWM output, much like we used in the heated seat setup in this thread, except you probably don't need a device like the Canny 7 that talks LIN bus if you are not worried about using the stock switches.  The stock seat elements are still based on variable voltage as far as I know, maybe someone can chime in that knows more, but that means if you use a MOSFET power supply like we use on the heated seat retrofit as it allows you to use PWM to vary the voltage.

 

For those of you still wanting to retrofit the factory seats here is the latest link to the Canny 7:

Thanks,

Kyle

Okay, here is the big update. The seat heating portion is done, everything is tested and confirmed to be working, the harness has been built. I am awaiting an enclosure for the power board, and bugging my wife into letting me get a 3D printer so I can make my own enclosure, on top of that I am waiting on the elements for the passenger seat. I haven't done much on the AC side at all, mainly because I don't have a set of seats to experiment with, feel free to ship me a pair of front seats, black leather, if you want to donate to the cause.

 

Okay, I have been coy up this point of completing the project while trying to decide if this is something I want to monetize for the few people who want this functionality on their non-fancy trucks, like me. But I will be honest, if you can take all of this information I am about to present and do it yourself you deserve to do it without giving me any cash. So to that end here comes all the information of what I have used to accomplish this project.

 

Seat heater elements (In lieu of stock seats with heaters):

https://www.amazon.com/gp/product/B001L6HYQK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

$28 per seat

 

Dash trim with seat heater or seat heat/AC buttons:

Ebay or your favorite GM parts supplier, can provide part numbers if need be

$100 or so

 

Switch Connectors:

http://www.mouser.com/ProductDetail/Molex/31068-1011/?qs=sGAEpiMZZMs7eK6h2EBtKuk1fUeupRrxcLsO5tRhpWs%3d

Less than $1 each

 

Pins (For about everything on this truck with small gauge wire, buy extras)

https://www.amazon.com/Automotive-Connectors-RECEPTACLE-CONTACT-pieces/dp/B00LVKB3S6/ref=sr_1_1?s=industrial&ie=UTF8&qid=1489871981&sr=1-1&keywords=928999-5

These can be found for cheaper elsewhere, do some looking, but lets say $10

 

Power board:

https://www.amazon.com/gp/product/B01N5VRZWF/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

$16

 

Controller, can't say enough great things about the guys who make this over in Russia. I am working on getting a discount to bring a bulk order over, check out www.cannylogic.com for more information:

http://www.ebay.com/itm/Automotive-Visual-Programmable-Logic-Controller-CANNY-7-/162358910401?hash=item25cd585dc1:g:jHAAAOSwVL1WC5Jd

$100

 

 

And of course various wire, crimpers, etc.

 

Wiring is simple. Use the upfitter manual but basically you are going to have these wires to hook up:

 

Controller:

Power (tied in with power and ground for the switches)

Ground

Lin 1 (Channel 9 to driver switch LIN)

Lin 2 (Channel 10 to pass switch LIN)

Channel 0 DO to Power board Signal 1 in

Channel 1 DO to Power board Signal 2 in

Channel 2 DO to Power board Signal 3 in

Channel 3 DO to Power board Signal 4 in

 

Power board to seats (both power and ground for elements will land on power board):

Channel 1 to Driver Heater Back

Channel 2 to Driver Heater Seat

Channel 3 to Pass Heater Back

Channel 4 to Pass Heater Seat

Are you or would you be inclined to selling a switch set up like this?

And then you are going to need the program in the picture I have attached. Don't worry, if you ask nice I could be inclined to email it to you. And I might even be convinced to sell a couple of these. The completed harness, controller and power board would run around $250, you would supply your own switches, and seat elements but I would make it in a way where all you would have to do is plug the switches in and tie in the 8 wires from the seat heater elements (Screw terminal, super easy).

 

Thanks for following along with this project the last couple of weeks and I will update you all when I start to tackle the seat AC.

 

Thanks,

Kyle

Are you making any of these switch set-ups to sell?

I have successfully completed this mod using Harlech's parts list, although I'm using factory heating elements. It works great and is relatively easy, but I did need Harlech's programming wizardry assistance 

The only draw back is the pulse width modulation used to control the 3 heat (L-M-H) settings needs adjusted as all 3 settings are extremely hot. I'm sure this has to do with me using the factory heating elements as they are designed to utilize a thyristor feed back signal to the bcm or seat module to control element temp and there is no way of utilizing it. This is by far the best/easiest way to add heated seats utilizing the factory switches. I'm planning on adding heated seats to the back seats using this same method. Big thanks to Harlech for all the work in figuring this out 

Is anyone will to make and sell this set-up

[silveradosid]

i had katzin leather and heater install in my truck, at first the 3 different settings worked but now the heat is the same on all the settings
