That's good info, confirmation that nothing about the components will get in the way once a standalone Arduino is created and tapped into the CAN network. I might be able to get to that before the end of the summer but no promises.
If you manage to get an arduino to work, I'll pay good money to get one.
So a couple of things from looking at these more closely:
- Connector 2066 on the Mustang has the pin 1 and 2 reversed from the Taurus
- Connector 2094 on the Mustang has pins 1 - 5 in a different order than the Taurus
- Connector 296 on the Mustang has the pins 1 and 2 reversed from the Taurus
- Connector 2091 on the Mustang has pins 1 - 5 in a different order than the Taurus
- Connector 2325 on the Mustang doesn't have a match on the Taurus.
I only changed one plug before. Not sure why I didn't notice the others.
If switching those pins around doesn't work, I think using the Taurus HVAC module along with the Mustang HVAC module may work. I will try tomorrow.
I think that according to the bottom diagram, I would disconnect pins 14 and 15 from the Mustang and plug them into the Taurus. I would also splice pins 1 and 17 on the Taurus to the Mustang for power and ground.
The only thing I wonder is does the Mustang HVAC send signals besides those for the seats on pins 14 and 15? And what issues will come up by disconnecting them and plugging into the Taurus?
Well, I tried the piggy back idea from the last post, and didn't work. Unless I had it wired up wrong. Cholmes, Stark 5.0 - any ideas? The last option I can try is to redo the pinouts for all the HVAC plugs.
Hi Jim. I don’t believe it is possible without an Arduino unit to send the needed signals to the Taurus unit via the dash buttons. I also don’t see how we will get the ventilation component without an aftermarket fan set up to receive the signal given the way the Taurus seats operate. Sadly, it is too much for me.
I plan to sell my Taurus HVAC unit and heat/cool dash buttons as soon as I can find reasonably priced heated seat blanks.
Oh boy, it's been a while. I've done all of Jim's oem upgrades to my car and loved every part of them....Thank you. Been following this one from the start and checked in from time to time. Had the climate control and hvac module in my ebay cart for a several years now. My issue was that my car did not come with heated seats. However, when I did the oem nav upgrade, I included everything for heated seats. I purchased aftermarket heating pads, but rewired them per oem by adding a couple of relays and tapping into the correct hvac module wires.
So here is my not so oem (but oem look) solution...could we still use the lower portion of the Taurus' climate control, but bypass the climate control module and use cooled seat button to power a relay for a set of aftermarket seat fans?
I like the idea, but am uncertain how such a simple system would work. The F150 group that pulled off the modification required something much more complicated.
That said, with your modding skills anything is possible
Here's a question if anyone is still around. On our mustangs with heated seats, we push the driver's heated seat button and it sends a signal to a relay through the white w/blue stripe wire coming out of the HVAC module (see picture below). For the Taurus, what wire does the cooled seat button activate?
