THIS IS GREAT!
I have been wanting to build one of these out of my arduino, im interested in this forum especialy, because I also have a Saturn, and from the look of your pictures it seem like they are close in years mine is an 2001 sl2 i curious what yours is is and if you have more pics of where you taped into the sensor wires.
Ive been looking at so many sites, and then I found this one in a Saturn so I decided this was the place to look around and of course view the relevant ads
What im really curious on is like i said some more photos, and if you sell a kit that can be wired into the arduino, or even a pcb with part,that just need to be soldered in, or a PCB, and parts list etc. im still new to arduino, but its an addiction you know, HEHE
PEACE and thanks for the info, and a great site
