Tools/Parts Needed:

1 - roll 18 gauge (or thicker wire)
1 - wire cutter
1 - bundle of tie-wraps

I used blue-colored wiring so it's pretty easy to see where the wires go in these pictures.

The wires for the oil temp and oil pressure should conveniently meet up near the driver side shock tower so I ran the wires together from this point.

I ran it around the driver's side shock tower and into the DSC box.  Then, I ran them through the wire harness that crosses over the engine and over into that empty compartment in front of the passenger side firewall.

Now, if you look into this compartment, there is some large rubber circle on the firewall that has a large rubber cylinder that protects some wire and next to it are three smaller nipples (red).  You will need to cut a small hole into one of these nipples and feed the two wires through.

Now, take a break and go wash your hands.  The rest of the stuff happens inside the car so you want clean hands!
