oil sender?

on the back of my 5.3 pointing straight up is a sensor that at first glance looks like an oil pressure sender. the wire running to it is a medium tan.

two reasons..

one, some people are using both sensors... for example, using a GM gauge and the stock LS1 sensor in the back, and the side boss for an autometer gauge..

two, the side boss can easily be tapped to 1/8" NPT... a standard that matches 95% of the sending units out there... but the metric hole on the back of the block is harder to find an adapter for.. easier now that a bunch of people have posted where to find it.. but still, it used to be harder. thats why they did it.

i have my boss tapped and plugged, but only because its the supply port for my turbos oiling system.
