After Market Parking Sensor for 986

[sam986]

Hi all,
I`m new to the forum and looking for some advice… purchased a 2.7 2001 boxster with 17 k miles on the clock. It looks and drives like new! The only problem is PARKING as the back side is big! Looking on the net for Parking Sensors found PD1Rear Sensors, which are attached to the back (inside) of the bumper…. Has any one installed one of these? Is the back bumper easy to take off and re-install? Is there a route from the boot (trunk) to the inside of the car so I can place the buzzer?
Any advice will help.
Thanks in Advance.
Sam
