I put a set of projector headlights in my mustang and the left plug on the wiring harness was broke so I wired it direct. I now have no left headlight or brights, the blue indicator on the dash doesn't even come on so I have to assume that I tagged a wire at some point and took out a relay. I checked all the fuses that I know of and they are good. any ideas?
There is no relay involved in the headlamps . Low or High beams ! Do you know what a wiring diagram is ? Free wiring diagram here http://www.bbbind.com/free_tsb.html Enter vehicle info. Year , make , model and engine size . Under system click lighting ,under subsystem click headlamps . Click the search button then the blue links .
Check wiring again at light. if fuse is blown both lights would be out. projector lights are one way flow , may have blowed diode in light

SOURCE: I need the wiring diagram
This is the diagram for the fog lamps ( headlamp is a different cell ).
If you are trying to add them to the existing wiring, do not expect the headlamp switch to cab fuse panel wiring to be there ( that is usually what is missing when you can find the fog lamp connectors under the front of the truck ).
File Save as so you can magnify it with the JPEG viewer you use.
Close up of switch

It sounds like you are confused about how your headlamp system is supposed to work. The DRL does not run on the High beam circuit, it runs on the low beam circuit. The fog lamps are supposed operate with the park lamps and also with the low beams, not the high beams. From your description, I would say that your system is operating as designed and you are having trouble telling High from Low. (Don't feel bad, that is why high beam indicators were invented in the first place.)
