Connection to Ignition circuit

[suzukitomcat]

Hello there
Recently purchased a 2008 2.0L Grand Vitara.
I am looking to install some aftermarket LED daytime running lights [DRL].
Have done this install before, on older vehicles, with no problem.
However am baffled as to the easiest place to connect a lead from the ignition sytem to the DRL controller.

Can anyone offer any assistance please. Thanks

Located and examined the wiring diagram on page 9A-57 of workshop manual.
Shows a white/red wire to terminal B2 on ignition switch and a white/green wire to terminal B1.
As B1 is connected to all of Lock; Acc; On; and ST my feeling is this is the one I should be tapping into?

Any comments please? Thanks
