im thinking of adding relay wiring for after market HID. HID makes popping electrical noise when switching on. Also want to add LED DRL as well. I see the battery jump junction under fuse box. But where are you guys tapping for constant 12 v battery hot access under the hood? Don't want run wire thru firewall from cabin to hood for battery...Thanks
I'm also wanting a constant 12V to a relay and some panel switches on my 2014 Prius V-2 3rd gen. Did you ever figure this out? I know, it's been over a decade since you asked this of the Forum...
@NutzAboutBolts has a video for accessing 12 point positive point at fuse box, for third gen. May be similar for the Prius c.
Thank you, such a quick response. I will check to see if I can install a new wire and putt it inside the passenger compartment through the firewall where I need it. I also saw in a fuse box diagram that there are 3 spares. #38 SPARE 30A Spare fuse #39 SPARE 10A Spare fuse #40 SPARE 7,5A Spare fuse I don't know yet if these are already wired and go somewhere or it's just awaiting to have a terminal to be inserted into it. On the fuse box internal #10 FR FOG 7,5A Front fog lights #13 RR FOG 7,5A Rear fog light I have to check and see if there's anything connected to these lights. I may be able to get 12V constant from these.
This is why it is ok to "revive" old posts. Simply because it will help someone one day. Posted via the PriusChat mobile app.
I decided to just tap off the 12V battery terminal with a ring lug crimp terminal... Internal wiring.
