Location of Factory Inclinometer

[jnr4817]

My 2018 Mojo did not come with autowake or an inclinometer. I purchased this off Amazon to keep in the boat. Been using the phone, but we also used navionics religiously so I need a permanent solution. When we speak of pitch and roll is it dead center of the boat at the middle. If I remember a previous thread the factory inclinometer is under the dash. My concern is will the slight difference in location of mine versus the factory, make that big of a difference, when shooting for a pitch of 8-10 and roll of -3-4?
