IR sensor problems

[BobcatProgramer]

I was working on the IR's and came up with a couple of questions that i need help with!!! The first thing that i have to ask is that when i had a sensor working, the signal on dashboard viewer was not solid it would either flash on and off or it would just be solid off! I don't think this should be happening so could you give me a hand.
The second thing is that I soldered one of these vishay sensors to a pwm cable and then the sensor imput was solid green no matter where the sensor was facing, covered or not.
How are other teams attaching thier sensors to the controller?? I tried a pwm cable that i took of the male end and I soldered the wire to the pins of the connector, and the problem I had was the imput always on (possibly from the heat!)
Can anyone tell me how they are attaching thier sensors and any other help on these sensors would be appreciated!!!
