Cool, that's a great site - I would guess this piece is part of a PI lighting package, part of this (at least very close harness) - EG1Z-14290-KA - "HEADLAMP PREP PACK, WIRING PREP, With Level 3 Headlamps, With Level 4 Headlamps". Tracing this harness down, I should find disconnected connectors or just cut cable - if so I'm planning to remove it. Already tight working on these freaking sideways mounted engines :-)
