Smile What is VCC on the drawings?

I have looked all over the Mega Squirt site to find what VCC in all the drawings stand for. Sorry I may be FU#$#$ up but I can't seem to locate the meaning.

A technique for reducing the amount of Radio Frequency Interference spread via power supply connections. VCC is a common name for the non-ground power supply line in circuits based on bipolar transistors.

When part of a circuit generates lots of radio-frequency noise, that portion of the power plane can be isolated from the rest of the circuit and power delivered to it via a low pass filter, usually a PI filter.

i think what he is trying to say is that vcc means power 12 5 or any positive voltage depending on where vcc is located. example on the mega squirt if u are looking at the ecu conector and the wire that is label vcc is going to the tps or map it usually means 5v or if its just a wire going to the ecu that its switched by a key or voltage coming from the battery, means 12v and this voltage is regulated.
