Ignition Power Wire Problems

Hey.

I have a 92 2.3L and have upgraded the head unit and had everything working great. I was adding a CB radio to the car yesterday, and that again worked just fine. However, today I again pulled out the head unit because when I was talking into the CB it was coming out of one of my car speakers, and I went and eletrical taped up everything again to make sure of no touching of metal. But, when i went to plub it all back in, nothing would turn on.

I have since, using a volt meter been able to see that my red ignition power wire is not working. The yellow, always power works giving my voltage, but thre red one sends nothing. I tried going back into the plug where the red wire emerges and testing back there, but still no success. I don't know of there is anyway to replace this wire, but I would not mind at all adding a new wire to takes it's place, I just have no idea where to connect it so it is only on when the ignition is on.

Any help would be much appreciated.

Yes the radio does turn on when the car is off if I connect both the constant power and ignition power to the same wire coming from the battery. This is ok, but I really don't want to have to remove my headunit's faceplate everytime I turn off the car for risk of running out my battery.

It seems that my cigarette lighter is not connected at all.

Running a new wire from the fuse box is something I'm intrested in, but I have no idea where to begin to find the right fuse for the ignition switch.
