I would reccomend tapping into the loom about where it passes the top of the rear left shock.
Here there is a decent amount of room to pull apart the conduit and expose the reverse wire (red wire with a green stripe) also after the wiring harness plug it splits into two.
here is a pic of where im talking about, and this is also where i put a fuse for the direct power to the reverse light relay
