Edit: Did you remove your bags for springs ? I have been reading through your post here and am a little confused. This post says you replaced your air bags,
http://www.elcovaforums.com/forums/s...t=38979&page=2 to me that means you had new air bags installed but I guess it could mean you replaced them with coil springs (sorry, I am a little slow on reading between the lines)
. But, I went over to the "other" site you said that you put springs in, if that is the case, try unplugging the compressor control module in pic below, remove the relay completly under the fenderwell and disconnect the battery, the light should go out.
P.S. Nice looking truck from what I've seen at the other site.
