Wiring is easy. The problem up front is the clearance.

With the stock antenna out, measure the depth and width of the available space with a tape measure, holding it at the desired antenna rake angle.

Then go to your local automotive chain store and look for a universal power antenna that will fit in that space. Wiring is simple; one battery +12v, one switched +12v from an aftermarket stereo "remote" lead or from a switch, and a ground strap. Depending on the antenna you may also need an adapter to fit your antenna cable to the aftermarket antenna.

The trunk is a very shallow space, so many aftermarket antennas won't fit. I found one that did.
