Some questions regarding +12V connection, fuse size, etc. ('14 A6)

0 votes
Just a couple of questions on a '14 A6 install (EVO ONE + MyCar smartphone).

The two +12V wires (E3 & D3) are to be connected at the OBD-II harness. Since this is a faily low current application so I'm wondering what the appropriate size fuse should be. Nothing in the quide regarding fuse size. In a few of the low-current EVO-ALL installs they specify a 5A fuse, would that be suitable here too?

On the same topic, I imagine the OBD-II wires would likely be thin-gauge, (EDIT: +12V looks like 18gauge from the guide photo)... It looks like the E3 wire is 14g. Since this is a low-current application, I'd like to step it down to a smaller gauge so it's not such a bulky connection at the OBD-II +12v wire. How small could I adequetly go on that?

 

One last question: Does the EVO-ONE provide power & ground to the MyCar smartphone addon through the data connector? They have optional power & ground wires for modules that don't provide power... Just want to get an idea before going into the install.
