Given that the pole coincides with the origin of the rectangular coordinate system and the polar axis coincides with the positive semi-axis of the x-axis, the polar coordinate equation of the curve C is ρ - ρcos2θ - 12cosθ = 0, and the parameter equation of the line l is $$\begin{cases} x=- \frac {4}{5}t+2 \\ y= \frac {3}{5}t\end{cases}$$ (t is the parameter).
(I) Convert the polar coordinate equation of curve C into a rectangular coordinate equation, and convert the parameter equation of line l into a normal equation;
(II) Calculate the length of the chord intercepted by line l on curve C.
