Default HID High Beam Help!

My high beams on my retrofitted HIDs stopped working after I had some gauges installed...

I have these components:
FX-R bi-xenon projectors
Ocular shrouds
D2S Bulbs 4300k
Morimoto digital ballasts

I used a plug and play harness to install my HIDs: http://blackflamecustoms.com/product...g-harness-p-83

The low beams still work and the high beam indicator is still in the cluster. When I switch on the high beams, the low beams turn off.

I do know that the shop installed new circuits straight to the fuse box... but they can't look at it for another week and I want this fixed ASAP...

Any ideas why only my high beams don't work? Is the fuse inline with the +12V to the battery for the high beams?

Thanks in advance!

I would check all fuses if you haven't already because it sounds like the problem is before the HID wiring harness. If you have a circuit tester then dive in and start with the headlight circuits. Good intentions aside, be prepared to chase alot of ghosts based on what people tell you might be wrong as it is difficult to diagnose electrical gremlins when you aren't there in person. Disconnect the HID harness and test for continuity of high and low beams and work from there. Apart from that just use low beams till the shop that did the install can look for the problem.
P.S. The best harness I've come across for your application is the dual relay setup that the OP uses in this thread. It seems a bit complex but really works well:http://forums.nasioc.com/forums/show....php?t=1482552
Also, What gauges were installed and did the harness work as it should prior to the gauges being installed? I ask because most PNP harnesses like your reverse the high and low beams. I know it sounds basic and silly but did you check the fuse in the harness? I've chased my tail for hours before looking in front of my nose and seeing the problem staring back at me.
