smlranger,
Did you get your high mount brake light issue resolved? I think JimM68 is pointing you in the right direction.
To add to what fireup said...
If you only have a single bulb filament that acts as both turn and brake lights, then a diode block is needed so the cyclops only turns on with the brakelights and never with either turn signal. Problem could be there.
