3.0csi euro

I found this on the web a while back, but the all white background was a bit much on the eyes to use as a desktop image, so I cleaned up the jpeg artifacts and changed the background to make the car pop out a bit more. Size is 2560 x 1440 pixels.

I'm trying to work through the under the dash wiring connections and see a Bitron 2043002 relay but I'm not able to determine what it does and where it connects to. I'm wondering if someone knows what it does and where it connects.

Got excited and then saw the extent of "patina"... http://sfbay.craigslist.org/sfc/cto/5715674445.html (not affiliated)
