More thoughts? It's a done deal, it WILL be done like this, it WILL work. At least on my car.. If someone else wants to waste 3 more very valuable CPU pins... I suppose I could wire up my transmission in a temporary way, on the floor, and at least prove the concept..

Do you mean to prove the multi-plexing concept in advance of you actually installing, or did you mean something else?

I mean I can wire the GPIO to the transmission, on the floor, and run the shift lever through the gears, to see it in action.. I can also spin the input shaft and monitor the turbine speed sensor.. Check the temp sensor(s)... etc..

That would be AWESOME! ! !

Fired up the trans for the first time yesterday, without the GPIO connected to it. Confirmed that forward and backwards work. I'm getting the pinout for the trans from a friend later today (so I'll update my 41te WIKI with that info). So it won't be long now..

I was daydreaming about this all day at work today.. I've got an aftermarket steering wheel with horn buttons under each thumb, those will be used for my paddle shifters, along with the floppy shifter I have, I'll be able to do either or, depending on my mood. This steering wheel has a normal horn button in the center.. What I want to do is multiplex the single horn wire, and have the GPIO trigger the horn relay when it's the horn button I'm pressing.. Cool, huh? I love multiplexing..

Cool for sure! I want to see this multi-plexing stuff work!

If your wife's minivan has cruise control or steering wheel controls for the radio, those are multiplexed circuits. It is a Chrysler or Dodge, isn't it?

It works! Posted a video on YouTube.. http://www.youtube.com/watch?v=krL6v1h6jog hehehe..

Simply awesome!
