Many thanks to @stark5.0 for this link. Heated and cooled seats are certainly possible and have been done with success

Just takes someone more capable than myself

If you manage to get an arduino to work, I'll pay good money to get one.

Here are photos of the pinouts for the plugs for the climate control system - blowers, blend doors etc ... top is the Taurus, bottom is the Mustang.

The Mustang has an Air Inlet mode door actuator plug that I am not able to match up with on the Taurus.

So all plugs match up except for the ones I circled. I did notice that a couple pinouts are different.

Here is the pinout for the Mustang Air Inlet Mode Door Actuator. This is not on the Taurus, it seems.

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.
