sensor wiring
 

How can i wire the sensors to my electrical system? i understand the white and black digital inputs, but for power, is it blue to negative (ground) and brown (+12v) to positive charges? Thanks!

You seem to be referring to the optical sensor.

The pinout can be found in many different places: on the side of the sensor itself, in any of the technical documentation for the sensor, and in many different threads on these boards.

I'm too impatient to paste a link to any of the numerous other threads which explain this in great detail, so I'll just let you search for it.

Search before you ask questions.
