Radar Detector Dome light hot wire
Re: Radar Detector Dome light hot wire
Awesome! Any knowledge on what color wires I would need to tap into to?

Re: Radar Detector Dome light hot wire
I would check the service manual electrical wiring harness for where that wire comes from and when it is 'hot' for a few important reasons. These cars are not your basic hot wire system harnesses any more, they go through modules and are designed for specific current draws for that designed circuit. Tapping into these may cause problems after an install depending on how much you 'load' onto that 'hot' wire you find. Just an FYI, as you know any accessory SHOULD be routed to a fuse center capable of handling the systems added (as written in your install manuals associated with what your adding). A friend up the street from me took his accessory 'bundle' on his 2011 2500 (finding a hot wire under the dash) and burned out his BCM because he overloaded the circuit that had that hot wire. Seeing as he was only a 'shade tree installer/repairman', he finally took the truck to the dealership and 1800 bucks later was back on the road. FYI...

Re: Radar Detector Dome light hot wire
Does not help this issue. Your still drawing whatever current through the circuit your tapping (through whatever other circuitry it is connected to). YES, YES, you can go straight to the FUSE BOX, like the installation instructions probably suggest. You do not need a fuse tap kit, but it might make the install easier if you've not done this before. They place an inline fuse in the accessory (what your installing) because they do not want people to sue them after something goes wrong (like melting wires/burning up your car). The installation manual probably says something like install to an accessory or hot point at the main or aux fuse panel and use the inline fuse after the hot line you tap into. These care are VERY sensitive to electrical issues, this is why you should not just tap into any hot wire in the car.. Good luck.

I didn't realise "radar detectors" were still a thing? After the commercial utilisation of GPS, most "radar detectors" / speed camera location alerts, made use of a GPS Database file you'd download to your device.
Then instead of active radar detection, they alert you to a known camera location (or other type of hazard) via the GPS database, based on the recorded known cameras in that area (you are driving through).
Some modern variations of "speed cameras" use digital technology and don't emit any type of radar. Using photography / ANPR instead!
