Hyundai Repair: 04 Sante Fe 6cyl - Oil Sending Unit, oil pressure switch, factory service manuals

Question
I am planning to install an AmsOil bypass filter and for the life of me can't find the oil sending unit.   I have tried to get a repair manual but none are available through Amazon, BN or parts stores.  Your help would be greatly appreciated.

Answer
The oil pressure switch should be just to the left of the oil filter, looking at the oil filter from the underneath and from the front.

You can view the factory service manuals at www.hmaservice.com.  The site requires Internet Explorer, and you'll need to register for a free account.  There's a very nice picture of the oil pressure switch (along with just about any other electrical item) in the electrical troubleshooting manual (ETM).  Simply click on the appropriate component location index in the General section.
