Bobby-
I have a pile of photos if you are interested. Here's a small sample. Note that this is a dual Lightspeed installation. The blue tube is reinforced urethane, fairly high-temp rated (though I don't recall the exact value), slit and installed over the OEM cable to protect from abrasion/dirt/cuts/etc:
The last photo makes it look like the plug wires are resting on the signal cables. They aren't; there is at least 1" of clearance.
