Rear parking sensors power cable

[B8yd]

I'm planning to fit some aftermarket parking sensors to my megane mk3 59 plate 5 door. I can't see the reverse cable in the boot lining. The reverse lights are in the boot(the part that opens) so I'm just wondering where is the best place to wire them into before I start drilling the bumper.

Thanks

Try searching for my post back in June 2017. I posted some step by step photos of how I fitted my reversing sensors. Link below.
