Superlift Speedometer Calibration box

Surprisingly the bloody thing works.Have had the thing installed for a couple months now, been working great, least after I exchanged the first one I got, that was defective and previously installed by someone else :mad3: (I could slap the shiat out of the nitwit that was doing returns at work for even allowing it to be returned)But the ruddy thing died the other day, which I thought meant, yet another install was going to be done with another new unit. Luckily thou, I found that it was only a week housing end on the inline fuse holder for the hot wire (if you install one, make sure it is not under much stress at all, might save you from the failure I had.Funny thing seems to happen when my speedo is not reading (haven't figured out if it is a common issue with TJs or not yet) damn thing would die when I pushed in the clutch or kicked it out of gear after I had been rolling for a bit. Silly jeep died 9 times on the 22 mile commute home from work :eek:Will have to figure that out next.
