also, do you wire the blue wire to the negative terminal on the power distribution board and the brown to the red? and if so, where does the signal wire connect to ?
thanks,

We placed ours 1.5 inches apart from the center of the photo-eye.
Brown wire is connected to postive 12 volts (red on fuse panel)
Blue is negtive (black on fuse panel)
Now we connected the black wire from the sensor to the white wire of a PWM cable and pluged it into the side car. The red and black wire of the PWM cable are left disconnected. In this configuration when the sensor sees a line, the input on the sidecar will go "low" - the programers will need to know this.
The white wire on the photo sensor is not used.
This is how we are going to be using ours, and we have done testing - modified our 09 robot with the sensors and everything is working great.
Depending on how high you have your sensors you will have to adjusted the contol on the sensor itself.
