I *think* the signal strengh is very weak.. I have never seen it brighter the the grayed out color.

The S-10 does not have a power antenna, but I believe it has a signal amplifier (It has a wire wrapped around the entire length of the antenna). I will check the Owners Manual to see if it lists the antenna as amplified or not.

If it is amplified, is the "Power Antenna Wire" (blue off the tuner cable) the correct wire to attach to the "Power Antenna" hookup on the Truck? It's the only Antenna wire that I have in the harness for the S-10 (that I could find)

Thanks for the replys, I love the empeg so far, it would be great if I could get the FM tuner working correctly.
