Replying to myself for posterity in case someone else has the same question...Thanks Brian. Did you end up mounting it somewhere else? I'm not 100% convinced the center console near the MTS control is the best location, it just seemed like an obvious spot
The blank space between the MTS knob and the ECT PWR switch is not actually blank underneath. Everything next to the transmission selector (seat heaters down to MTS) is all part of a single plastic part. The main wiring harness for that mess is DIRECTLY underneath that blank spot.
Sorry I don't have a photo but that's where I wanted to put mine, however when we got the center console apart we discovered it wasn't possible. Since all my blanks are currently in use, and I didn't want to then go through the effort of converting them to an spod, we ended up putting mine in the spot where the phone holder is under the ashtray. Really it's fine since modern phones (iPhone X and newer) don't really fit correctly in this spot anyway
