Sounds like you wired it wrong.
As soon as you do something truly custom, it no longer becomes a "Subaru" issue, and more a "only-you" issue.
guys, I created a custom program for my iPhone that links up through the Bluetooth. It worked yesterday, but not today, any idea??
Start by tracing your wiring from the battery and make sure you only relocated the major runs, no other leads. Maybe there's one wire you snipped off and reconnected in the bay that you shouldn't have.
