Hi from SA

rear: under chrome strip at the as far laterally as possible.

Front: grill under lowest slat. As far laterally as possible.

Exc. locations & have the center-to-center spacing of the Sensors 17"-19" apart.For Front could be under the lower chrome slat or below on the very bottom shelf of the grill,whichever is the most level surface,easiest to mount.The Sensors HAVE to face straight forward (& level)-do not follow the curvature of the Frontal area( & same for the Rear). If you put the bubbles outward,they will be almost centered equal triangle spaced distance from HLs,& lower turn-signal lights & both sides of Front LP edges.

Should the bubble of the sensor be on the inside or outside on each side
Or does it not matter, I would think an extra inch may make a difference
I know this is basic for most of the users but can't find this info
I hope the snow is not too deep there
Best regards

You're correct an extra inch doesn't really make much difference b/c the ALs are so sensitive.
