This will be plug & play providing your car has the black connector dangling behind the O/S boot side panel
& the 2 pin connector with green & red wires on the N/S of the rear shelf.
If you dont have these connectors then dont despair as I can make up a simple wiring harness for you which taps into the reverse light wiring in the boot, the only drawback being it will be independant & not diagnosable by a T4 (Testbook version 4.Computer Diagnostic System) but it's hardly rocket science anyway
£60 Posted or £70 if you require the extra wiring
