Fasttrack O36 switch problem

I went yesterday over to the VGN brakemans layout to wire up a couple
remote 036 fastrack switches. I found a problem with one.
on the controller when i wired the switch(with a longer wire) i lost the
indication(the red and green lights) on the controllers,but the swicth would operate. i rewiredt he controller and had both lights burning all the time and the switch would not operate. so i did it again and no lights but switch operated.
does any one had any ideas on what i did wrong?
Thanks for any advice.
