Low Beams not working when everything else is.

Look, I know that there are a million posts about this topic but i cannot find the answer. I purchased an aftermarket headlight assembly with angel-eye LEDs and HID lowbeam headlights. When i had gotten done with wiring everything together, I turned on the lighting assembly. First the driving lights (the LED angel lights), they worked fine; then I turned on the lowbeams, they worked fine as well.. for maybe 5 seconds. They abruptly turned off so I assumed that a fuse had been blown; I checked all headlight fuses and they were fine. Then i swapped the headlight switch (the big one to the left of the steering wheel) and it didnt fix the lowbeams. I then hooked up a volt meter to the wiring harness of the headlights and individually checked each signal output, the only ones not working were the lowbeams. Now i can only assume that the wiring or switch is compromised. Help me please before i go and spend $150 plus on mechanic who will tell me that a wire is loose.

Ps. I know that the HID bulbs for the lowbeams are not blown because i wired them into the driving lights wires for diagnostic purposes and they worked fine. All of the functions on the assembly work besides the lowbeams.

Update

Was driving home from work tonight (with my highbeams on) when a stopped me at a light to tell me that my brake lights arent working as well. Hmm, i believe that these two must be linked; something is probably preventing the lights from coming on.

I checked at the headlamp connector. I turned on every swtich in the cabin individually and then checked the wiring diagram to see it the wires matched up. (im using a wiring diagram off of the first google photo in this search "wiring harness vw jetta repair 2 index listing of wiring diagrams 1968 vw beetle wiring diagram" ; the diagram matched perfectly) And the blue wire, 2 (LB), is the only wire that does not output voltage when i do turn on the specified switch (the lowbeams) No matter what i do i cannot get power to that wire.
