I don't have that tower, but a shop vac and dental floss works great to run the cable, once you decide on where you want to drill the holes.
With the FCT, you can run the cable from the passenger seat compartment up through the center of the mounting base of the front-port tower leg, so you don't have to put another hole in your fiberglass. I don't know about the Titan, but there should be lots of good Malibu info and opinions here:
