Trem Lune NSL32 HELP

[FuzzAldrin]

Ok, I got this thing  and I am clueless as how to install it on the board. Do I take the other 2 legs and solder an LED on them? Then cover Both with tape?
Anyone care to explain or show me a picture of theirs?

It has 4 legs, right?

It's a complete package containing a light-dependent resistor and an LED ... 2 of the wires are the LDR, 2 wires are the LED ... all 4 wires go in the board.

Remember ... the polarity of the LED side must be correct, or it won't work.

  Here's how I did it.
  Put a sufficient current limiting resistor on the LED.
  Hook a DMM up to read the resistances of the LDR.
  Add 9v to the LED, if the LDR doesn't make the resistance drop on the meter, the leads on the LED need reversed, LdR resistance should drop fast and settle low when LED is powered.
  Or you can get good with the DMM at recognizing diode #'s, ballpark the LED foreward threshold, the DMM will say something reasonable when the LED is turned around the right way.
  What's the right way?...read the DMM markings..
  but I just grab a visible diode, put DMM leads on it to see which way around makes a 'regular' number for it's FT, and note which end of the LED makes it read the threshold #, then when the invisible LED = FT, I know where the cathode is.

Isn't it marked, like the Vactrol is?
