I've never seen that part... Though have not pulled the battery yet. But then again, I screwed-up on the last discussion we had about the additional fuse box under the bonnet. It does exist on the US cars. I was just being brain dead and didn't ever look...

I'm still trying to figure out my mystery BEEP BEEP BEEP at certain parts on the track. I originally thought it was my track timing device, but it happened again last weekend and I wasn't using the GPS timer. The funny thing is my car is gutted and not even the key alarm chime is connected anymore.

I'm going to be relocating my battery to the rear in the next few days, so I'll keep a look for your MYSTERY part.
