I'd like to tap into either the mirror or dome light power for my radar detector install (like this guy did in the E36: http://www.m3forum.net/m3forum/showthread.php?t=445897).

This is for a 2017 M4 coupe.

In our case it's not clear what wires are what, and the connectors are much smaller than they used to be and the RJ11 taps won't (easily) work.

Here's some pics to show:

This is what it looks like under the plastic cover that covers the mirror mount:

Anyone know which of those wires is ignition switched +12v/ground?

Here's the tap I bought:

Amazon.com: Radar Mount Mirror Wire Power Cord for Escort Radar Detectors With Inline Fuse RJ11 (3005201): Radar Mount: Car Electronics

Separately, if that doesn't work, how do you get the overhead console off to access the wiring that powers the dome lights?

Thanks.
