Subaru Impreze Parking Lights

My girlfriend's 1998 Subaru Impreza Parking Lights came on and won't turn off even after shutting off ignition, turning the lights off manually and removing the key! I saw a similar post by @wsander on the 20th of February. Both the front corner (parking lights) AND the rear tail lights are on full-time now. This was right after I did a tune up where I replaced the air/oil filters and oil, added new oil and oil additive, did a compression test and replaced the spark plugs. The only electrical I touched was the wiring clip to the MAF which I disconnected to move the air intake for access and replaced when I was done. And the washer fluid reservoir which I put back while it was dark and accidentally draped the two sets of wires over the battery clamp-down bolt when I replaced it so the wiring harness that those wires were routed into got pulled up a bit - but it didn't look excessively stressful - the sort of pull you might put on a bundle of wires to move it for access or something. But I'm guessing that has to be the source of my problem. I'm also guessing it is a relay of some sort that is busted or shorted to the always on position, but where do I find it?
Right now I am having to remove the 10A 'lights' fuse every time I leave the car to keep the battery from dying. PLEASE HELP! My girlfriend was super stoked that I changed her oil and tuned her car up but now she suspects that I messed up her electrical and don't know what I'm doing! Help me redeem myself. Thanks!
