Well I finally got around to installing the Scangauge II. I picked it up from AutoZone for about $150.00. Installation was very easy. I disconnected the OBDII port and "relocated" it to just about he fuse block. This way, I can keep the factory look of the fuse cover. This thing is awesome! It is very comforting knowing you are only a button away from REALLY understanding WT, VLTage, and other crittcal engine stats. My truck's WT runs between 184-190 most of the time. Pictures below.
