yes u can do that, but your grille blinkers will still blink when you signal them, so having them disconnected totally (remove the harness completely) will avoid that because you will be using your built-in blinkers in your hid lights instead. but yes, you can use the ground wire anywhere, u dont necessarily have to tap into where I told you to.. and as for tapping it elsewhere, yes any circuit that has +12V when the car is on will work, its just that the DRL circuit does that already so I recommended that one, but ur free to re-wire.
