The cable shown in second pic looks too large to be a simple iPod connection. IMHO
I had a switch like that for Hydrogen system, HH2Go, 2 parts Hydrogen - one part Oxygen - when you break the covalent bond (using a small electric charge) BOTH can be burned with gas. In fact, it is like running on Race Gas! And the engine LOVES IT! No nasty carbon deposits!
Here's a pic I still have from the installation. I was getting 30+ MPG in a Mercedes and 22 MPG in a Dodge RAM 1500 while driving like I owned a Pcar! The power was incredible.
And no, I am NOT TALKING about these crappy ebay deals that promise what the system cannot deliver! CA trucks have been using a larger, similar system for years! I compressed it and fit into my car!
Alas, the lawyers nixed the idea. Too bad since I was almost doubling my mileage. My truck went over 100,000 miles using the system and the Merc put in about 60k.
