Yes Jeff, it is a Freightliner.
I pulled the dash off and it seems the gauges actually have air lines conected to them. I traced the lines back to a manifold looking thing of sorts. It seems as though the gauges are ran by air. The warning light has a little clip with about 5 little white wires, it apeared a little loose but all else looked good.
Everything I have read talks about digital signal to the gauges. Sort of confuses me that the gauges have air going to them.
I really apperciate the feed back. I will check deeper into it with the information you have given me.
