Which fuse to tap off of for 2014 q60S?
Was wondering if anyone has tapped power from the engine fusebox. I just installed an AL priority parking sensor system- I took a wire from the fusebox which is in front of battery and used the heated seats fuse.
The problem is its always on even with the ignition off!
Any solutions other than adding a switch to the circuit?
Any other place to tap power from UNDER the engine bay that switches on with ignition?
Instead of wrapping a thin wire around one of the ends of the fuse- would I get different results if I used one of those "add a circuit"
My ground is hooked to a ground hookup which is behind the passenger headlight.
Thanks

I prefer using the Add-A Circuit units--they are just cleaner.
The Accessory circuit shows in the FSM as Fuse #19 and #20. #20 would be the preferred circuit to use, as it only has stuff like the power sockets in the center console and dash on it. However, those fuses are likely located in the cabin fusebox, not the engine box. I cant seem to locate a diagram of the underhood fusebox.
You should look for something that would normally be powered only with the engine on (I would have thought the seat heaters would be like that, though) like the windshield wiper circuit. Try to choose a fuse that is 10A or lower---most Add-A-Circuit thingies are only rated for 10A.
Whatever fuse location you use, pickup a new fuse for the device you are connecting in whatever amperage fits the device. Pull the existing fuse, insert into the correct slot on the Add-A-Circuit. Insert device fuse into the remaining slot and insert the whole thing into the engine fusebox.
I would suggest you try using the seat heater fuse again, but with the Add-A-Circuit and see what happens.

Just looked at my car. The fusebox near the battery has 3 10A fuses you could use. However, the Add-A-Circuit unit may be a tight fit under that cover. The good news is it sits below the battery cover itself, so you may be able to just leave the fusebox cover off, should there be a fitment issue. Good luck!
