Radio harness power

Installing an aftermarket head unit and I have it all wired up and the unit won't turn on. 1989 fc and I checked the fuses and they are fine. Using a volt meter I found out that I am getting .003 volts at the constant wire and my ignition one is jumping around, this is at the stock harness. Any ideas on what is wrong?

Taken from the FAQ:

What are the wire colors for adding aftermarket radio
LTBlue/Red= 12v+
LtBlue/White= +Accessory
LtBlue/Yellow= -power ant trigger
Red/Black=+ Lumination
White=Factory Amp Turn on

Ground to the body, use the 10mm bolt behind the center console front drivers access panel. Do not use the Red/Black as ground it will damage the interior light circuit and dimmer in the car

Thanks for telling me something I've already read. I made sure the colors matched. I'm saying the light blue and red wire has no power going through it. I've also searched and read the faq.

I apologize for the attitude but if you had read what I had asked you would see that I'm saying that the stock harness is receiving no power. It is not anything to do with the wiring of my radio.

Figured it out by pulling every fuse. Only blown fuse was the "ROOM" fuse. For some reason this fuse was making it so the radio didn't come on.
