How to check if ECU is getting power input... Ideas?

If I take a multimeter, what should I be reading on the wiring harness going to the ECU? I was told the power wire which powers the ECU is red.

I need to know if my ECU is even getting power, and I need to do some wiring tracing... if anyone knows... please inform me.

Thank you,
-Darren-

Look in the service manual... you can figure out pretty much anything from that. If you don't have the service manual... get it off my FTP
