Uprated headlight loom and battery drain

Is it possible for an uprated headlight loom to be draining a battery? 

The car hasnt been used since September  but always starts no matter how dead the battery is, longest its been left was 3 weeks without being started and thats because it was covered in snow and I didnt want to take the cover off but it still started.

I fitted an uprated headlight loom a couple of weeks ago and now it is as if the battery isnt even connected, no lights on the dash at all.

Nothing else has changed, car has no alarm or stereo either

The ones I have made, or bought haven't shown any issue, but not all looms are made the same, and if your
Battery is draining then you probably need to figure out which circuit is causing it I will post the link to how to determine a parasitic draw.

That video is actually really useful and doesn't involve any shouting, both of which are very unusual for an American video.
