 It's about $70 for either OEM or a Bosh unit.  Evedeintly that 3 pin GM
 weather pak connector used on it is gold plated or someting.  Does any
 one know of another vehical that uses the 3 wire type and is less
 expensive.  I don't want to pay another $40 for the connector.

I thought the reason the 3 wire was so expensive was because it was heated?
