Does anyone have a link to the fuse box diagram? I want to hardwire a dashcam and ideally there will be one fuse that always has power and one that turns on and off with the car then I can get sentry mode working. My second hand car only came with a quick start guide not a full manual.
 
I found the user manual which basically says only fiat dealers may change fuses with no other information. I guess I'm going to have to just try some but would prefer to know what the fuses are for first
 
I've used a 70mai Dashcam hardwire kit and plugged on F94 fuse (12V outlet) and the spare fuse, below F47, for the power when off (ACC)

Thanks where did you get this? It looks like my hardwire kit comes with 15amp fuses so I was thinking the 12v but didn't know what else to use, hopefully mine is the same as yours and I can use the same.
 
I was just thinking about the F49 and the F94 :) Although you should confirm if they are powered directly or through ignition.

You can certainly use a fuse smaller than 15A for the camera. 5A or 7.5A is more than enough. I used an adapter that keeps the original fuse and adds one for the device.

I bought this https://www.aliexpress.com/item/1005007620188635.html which seems to replace the current fuse with the supplied one. There is no information but being blue I am assuming 15A. I regret not paying better attention as I assumed this would come with tap adapters but I assume if I only replace 15A fuses or use an unused spot then I should be fine

The only concern I see with this adapter that is in your Hardware Kit is that if you use the fuse used in the F94, it may not protect the HardwareKit, since it consumes very little and may not burn if there is a failure. For this reason, I used to connect my Hardware Kit to a TAP Adapter, because I keep the 15A for the 12V outlet line and leave 5A for the HardwareKit, so if it has any failure or overload, it burns before the 12V outlet line.

Yes it does seem like a flawed design to me. I think I'll try it anyway. I think my fuses look the same as yours, all filled on the left and 2 spare on the right. Will use bottom left for the always on and the spare on the right for the att. Thanks for your help.
 
I ordered didn't work. I'll send it back

Unfortunately that cable I ordered didn't work. I'll send it back but I'm thinking it's probably better to just get the slightly more expensive obd cable
I'm afraid to use the OBD port to constantly power an external product. An overload could damage some system in the car and not just a blown fuse.
