3 wire proximity switch help

I connected them the way you said and it works. I conected the black wire to the imput and the 5v on the BOB. Now I'm trying to connect them in a junction box and the Y+ will trip but the Y- won't when there conected together. Can you tell what you think is wrong.

I used 1 4300 ohm transistor on the end at the BOB for both switches. I'm wondering if all the switches have to be run back to the board with seperate transistors.

They are the two blue switches on the bottom of the picture.
