Mystery Antenna

I had a previous post but I think I accidentally deleted it.  I was wondering what the third antenna was for.  I found paperwork in the motorhome that says it was a cell phone booster.  Meantime I have to continue cleaning out the overhead component compartment and repair dried up insulation, see attached.  While I was looking for the cell phone cable end I found a switch under the dash flip up and a plug by the diagnostics plug that someone unscrewed from under the dash and had tucked under the dash. Does anyone know what these 2 unknown items are for.  Thanks for the help.

@john,

I agree the antenna is a cell phone booster. Probably old technology. Would be surprised if it still works. Can't help with the switch.

see ya

John,

Try the search function on the Forum...search for "mystery switch" or "blink switch".  There are many threads talking about these switches found under the dash.  However, there are usually 2 switches mounted close together, and you only seem to have one.  The switches may or may not be labeled.  They usually are used in some way to retrieve stored codes for engine, transmission, or ABS brakes.  Perhaps one of the old threads on this subject will give you a clue to what your unknown switch does.

One of those plugs looks like a hookup for the ECM (round one) the other do not know
