help with CB problem please

Good day, everyone! I found this site while searching for a solution to a problem I'm having with my CB.

I had it in my '97 MACK tri-axle dump truck, and it worked perfectly. Then they bought me a 2004 International. I've been in it in three weeks, and I cannot get the CB to work.

I can hear and transmit only to trucks I'm running with. With the RF gain all the way up, and the squelch all the way down, I don't hear any static.

My radio is a Cobra 29 LTD Classic. The sticks I'm using are off my son's Kenworth T-600. Currently, only one stick is connected to the coax, although both sticks are mounted on the mirrors. I'm using the overhead cubbyhole to hold the CB, and have it connected to the factory installed coax in the cubby. The power cords are connected to the terminals on the dash. Looks kinda shabby. I'd like to connect the power cords to the ones in the cubby, but don't know which wire is "hot", as one is white, the other green-and-white, not red & black as one would expect.

I've been told that the mirror mounts on my truck do not have a good ground, and supposedly that is the problem, but I don't know how to remedy it.

Thank you for the reply Johnny. Initially, I had both sticks hooked up to the factory coax. When that didn't work, I bypassed the factory coax and hooked up only one stick using the coax I had taken out of my Mack. Still couldn't hear anyone I wasn't next to.

It has been suggested that I run a dedicated ground from the back of the radio directly to a bolt on one of the door hinges using the shortest possible wire. Not sure how to do that.
