    Hey, got this yellow box (computer I guess) under the dash. Anyone know anything about it? It says Dana Corp. on it, so I'm guessin its got somethin to do with the 4wd. I donno. It's in an 81 K5. How important is it? Thanks.

    If it is above the glove box it might be an ESC control. That is where mine was located on my 85. I don't know if they had it on 81's though.
