LS Lesson Learned #3.
some guys can pick up on this just by reading stuff on the InterWebs but I'm too dumb for that, so I didn't realize this until I went to plumb and wire it
the 1999-2007 LS truck engines that we use for LS Swaps do not monitor the Oil Pressure with the computer aka the PCM
let me say this again, the computer does not care what the Oil Pressure is on these engines, so a lot of guys unscrew the $55 dollar OEM oil pressure sending unit (located in the stock location on the top driver side back of the engine block) and screw in their aftermarket sending unit in it's place (using a metric to standard adapter of course) and just run their aftermarket gauge or their stock oil pressure gauge
* I am quickly realizing that the jump from our trusty distributed carbureted second generation SBC engines to these Third Generation LS based engines is not as intimidating as one might think, here are four examples:
1. they only use one computer for both the engine and transmission management not two
2. the computer does not manage oil pressure
3. the earlier ones 1999-02 are still drive by cable instead of drive by wire throttle pedals
4. they still use mechanical radiator fans - less complicated wiring
