I finally went out and bought the IR reciever module again.. i still do not know the correct way to wire it becuase I dont have the pinout or datasheet.
The pictures are attached below, I took shots of many angles.
From looking at the module head on (with the black bulb facing you)
what should the pin out be left to right?
Is there ANY way to tell if the pinout is correct?
Will the data line be 0v or 5v when it is wired correctly with no IR being emitted on it?
Thanks for any help!

Ps. I already know some of the pictures are blurry no need to tell me.
The problem with these IR receivers is that unless you know the part number you will not know which remote control carrier frequency it is designed to work with.
For example, the Vishay TSOP48xx series datasheet shows seven variants:
If you are lucky, it may be a 36kHz type which works with Phillips remote controls. (They use the RC5 standard protocol which can be decoded with a PIC micro.

How expensive is your part? I did an AVR project last december with an unknown and it worked fine. Go to Nigel's website and wire it up just like he shows. Don't cut corners, you need the cap and resistor. The output should be HIGH with know signal, drops LOW when it detects. The center frequency is a guideline for best performance, anything close will work to some degree. I used the remote from VCR and oscilloscope to verify it was working. Didn't know the frequency of the module or VCR remote, and all was well.
care to name one please? Sayal is pretty much crap as you know... I went to ACTIVE in mississauga.. it was alright.. except for the fact that they are selling a pic16F877a for 20 bucks!!! RIP OFF.
The source doesnt sell IR reciever, I cant find this damn IC anywhere except sayal!!!
When I order online (or by phone) at Newark or at Digikey before 8:00PM then it is delivered to me the next morning.
Sayal has good prices on some things and Active is there when I need someting in a hurry.
The Source sells cell phones and consumer products at full list price. They might have some old electronic parts leftovers from RadioShack. I have never bought anything from The Source.
But it will trigger from any random occurance which passes through the IR receiver, this is why you require digital coding on the data stream, so the PIC can determine if it's a valid signal or not.
