OBDII Splitter cable

Just looking around at all available OBII scan cables and software and seems to be a huge selection of stuff, let alone wireless and stuff with little blinky lights to tell you if you'll pass emmisions just a wild selection. I can see where some people would buy some of these things and someone is making money... some might acually be useful!

Then I bumped into this and thought, "Cool!" "Cheap!" But then why?

OK you could use it with this and still hook up a scantool!!! "Cool!" "Cheap!" Still wondering why?

that "box" one looks like it's used to confirm that modules are responding on the circuit when polled.... otherwise, i have no idea why you would need LEDs on the circuit.

the splitter cable.... that could have quite a few uses, some nefarious, others confusing.

All that seller's cables are cheap. Prolly based overseas where labor costs dollars per day.

You know what that OBDII ECU Simulator is all about, right???
