I don't have any photos of the install, but it wouldn't really show anything anyway - just a fuel tap right behind the LH throttle body. I'd have to remove the tank to show it properly, and that's not a fun job.
The tap I used was:

It was a few years ago, but I had the tank off for another reason. I identified the hose from the Stepper (in the engine 'V'), cut it, re-routed the hose under and behind the LH throttle body (for convenience) and inserted the tap.
I leave it open, unless I get a high idle - usually when the engine gets extremely hot. Slightly more engine braking when closed, which makes for less smooth throttle control.
