No low beams

Since it has been modified, you are on your own here.  I would verify whether the relays are using positive or negative switching (both on the coil part of the relay as well as the switch part of the relay).  Then troubleshoot the lighting circuit from there.

On my own, wonderful, that's why I came here for help. Facts are the system worked fine until sitting for 6 months, the low beam bulbs are on when the high beams are on, therefore the bulbs are good. What remains is why the low beams are not getting power when on the low setting. Any help other than "your on your own" would be appreciated .

Does your sport system with upgraded harness use dual filament bulbs for low beam? I believe the 9007 are dual filament so you’d still have the low bulbs working with high beams engaged if just the low beam filament went out. 
 

If it’s not that, does your kit power the bulbs from the battery (off a relay?) I’d check that and make sure your connections are good, and check the connectors at the relays.

 

I have the Daniel Stern kit, that’s where I’d start, assuming yours is similar.

Saying that you are "on your own" was a poor choice of words on my part.  I apologize for that.  However, the forum will need information regarding how the your headlight relays and bulbs are wired since your current headlight wiring is not likely to match the FSM wiring diagram.  Also, if you let the forum know your skill set, then the forum can ask the right questions and help get this figured out.

It is possible, although not likely, that both low beam filaments are burnt out.  You don't want to skip this step.  While you are checking, identify the bulbs - that will help with troubleshooting.
