bgilbert said:I looked under my dash, and right next to, just to the right of the hood release, I found a plug. What could this plug in be for? Maybe the previous owner bought the tach package and before he sold the trk to me he kept the tach unit. This is two small drill holes on top of the dash about and inch or two apart, where maybe the tach was??? I wish I still had the previous owners #. .
Anyways could this plug in be for a tach? Thanks Bill
Oh and you got my moneyThierry said:The plug you are talking about is the snow plow hook up, this is one of the plug hook up to use the factory wiring set up for the 89-early 91 trucks with non intercooler.
