Hey guys, I gave up on building a carputer coz it were doing my head in and now i've gone back to it and can't remember anything I did

Basically I am after the carputer starting by itself,
black to black on battery
red to ground
grey to ignition...

is that right or am I missing something?

Thanks

I may be wrong but that wiring does not sound right
to me. Wait until someone else picks up on this, in
case you damage it. Change your title to Carputer
Wiring Problem, help needed.
