There's a nice DIY for V1 hardwire install on Evosport for a W208 and describes that a grey wire with red stripe is hot only with car on. Well, I figured out how to remove the center overhead console and there isn't a similar wire. There are several wires and I'm sure one of them is hot with ignition on, but which one? It would be nice to install in this location because of the close proximity to the windshield and no need to run the cord down under the dash. I've done a similar install on my e46 and it's very clean. Any ideas?
Thanks.

After testing almost every wire up there, I found one that is hot with the ignition. It's a grey/blue wire on the far left. I'll post pictures later.
