Fitted an auxiliary ACC fuse box in my driver's footwell. Butchered a set of jump leads for cable and installed it on the outside of my drivers footwell. I'm RHD in Scotland, so no idea how this would translate for LHD vehicles.
Positive 12v Power came from the wee accessory wiring box in the engine bay and in through the firewall grommet. Negative feed was straight into an earth connector nearby. Excuse the redneck cable tie install, but it works well and makes it easy to remove when I need to wire in new gear. It will stay like that
Into the new fuse box went:
* Nextbase 622 Dashcam with a Nextbase SD card. Will add a rear camera to it in time
* Ali Express Self dimming rear view mirror with temperature, time and compass. Compass needs attention, I'm permanently SW at the moment, so believe I need to drive around in circles to calibrate. It's bigger than stock mirror and doesn't have that claustrophobic magnification thing going on that the OEM one had. Not tested the self dimming yet. It knew the time already, just had to set time zone, so some clever tech in there. The shoe is compatible with OEM, bolts right in. The vendor asked for photos of my mirror and confirmed model and year - they will be receiving a 5* review. I will provide links if people are interested (non affiliated)
To be installed:
* Garmin Satnav - I had the wrong wiring kit, but easy to do now I have the fuse box ready to go
* USB sockets
* Possibly HiFi gear depending on how I choose to do that in the future
