Looking for an engine running switched wire in the trunk.
I recently picked up this 2006 E320 CDI. Runs and drives excellently. I've been chipping away at the basics of worn out seals, fugly armrests, wtc... I'm sure I'm keeping it for quite a while. I'm looking to add a couple of air compressors and a tank for onboard air for various pneumatic things. Wanting to add air shocks, horns, and a quick connect to fill tires if needed. I have all of the air squishing stuff and am assembling it and painting it matte black to kind of disappear it in the trunk. Power supply wise it makes sense as the battery is back here.
I have relays wired up, it's basically all ready to go. I'm just looking for a switched hot back here(for convenience mainly) that is hot while the engine is running. I've been scouring the web and having no luck finding the definitive answer.

I've fallen into that trap before on other vehicles. Specifically I found an engine running hot wire while it was dark out. Turns out that wire is hot while the engine is running and the photo eye sees darkness :/. My stereo in my pickup only worked at night for a week before I got to work on it during the day and the light bulb lit up.
I was just hoping somone knew of an engine running switched circuit in the trunk that I could hook the relays for air squishers up to.
