Auto Meter plumbing locations

[hossdoc]

I recently purchased a set of Auto meter Phantom II gauges, Oil pressure, water temp and voltage. I was not anticipating that the oil pressure and temp gauges would come with 10 feet of tubing. I had figured they would have sending units which would screw into the engine as the stock gauges did. Can anyone give me some advice on the correct location for the pick ups on the engine for the water temp and oil press gauges? Are all auto meters like this or did I get the wrong set???
