What is the other plug for, on the oil pressure sender?

After doing some electrical work. I noticed that the wire that goes to the oil pressure sender "y"s off about 6 inches downstream. It connects to that other little plug that sits right above the sender. What is this plug and wire for? It has a yellow wire with red stripe I believe. The plug is a single wire connector. Looks like it is just connected to the upper intake manifold with a resistor or something of the like.

Thanks HAILERS! I though maybe it was a resitor to calibrate the same oil pressure sender in all FCs with the different guage clusters. What is the condensor supposed to do? And why did Mazda put it on the UIM? Seems like it would have been alot easier to just put it inline with the sender wire.

I really don't know. IceMark might know. I'm not electrical in nature.
