I just got the under dash plastics removed and was going to install the traction control module when I realized that when the manual says "reads ground" it did not mean read as in a label...since I have no idea how to read ground (I know how to read for a voltage signal) I had to give up.

Which of the 4 wires on the TCS button do I splice the orange and which one do I splice the black wire into?

I have an 05 350Z

If there is concerns that the terminals have changed then how do I read for Ground???

Help is appreciated

 

never mind, I got my answer on the KP Tech forum.
In case someone else needs it here it is:

pin1 is a blue yellow wire which is the one you will attach the orange wire to

pin2 is a black wire which is the ground wire which the you will connect the black wire to

pin3 is a red blue wire which is an illumination wire do not connect anything to this wire or you can burn up the chip (trust me ive done it before and its not fun when you put it all together and then it doesnt work)

pin4 is a red yellow wire which is also an illumination wire and will have the same consequences as if you connected it to pin3
