Learned much from this helpful forum.
Its almost finished and is now going to be molded so the outside will be smooth black plastic.
Now, I just have a question, My TSX is a NON-Navi model so in the PCM, there is a pin for the VSS Wire but no wire is present.

How do I connect the VSS wire from the Z1 to this Pin? Will I have to buy some wires or can I use the existing wires from the Z1? I'm just not sure if its long enough to reach the PCM pin connectors in the footwell on the passenger side which this VSS pin is located.
