Battery Voltage
Intake Air Temperature (IAT)
Engine Oil Pressure (EOP)
Engine Coolant Temperature (ECT)
Engine Oil Temperature (EOT)
Transmission Fluid Temperature (TFT)
Miles Per Hour (MPH)
Miles Per Gallon (MPG)

I looked up the instructions for a couple hitches we have for your 2003 Mercury Marauder, and called the manufacturers of all the hitches we available. You would have to slightly modify the exhaust system. On the passenger side, you would unbolt an exhaust hanger, and re-bolt it to the hitch once installed. It is actually very easy, the bolt location is only moving a few inches. You should not have to cut or weld any of the exhaust.
I will include a link to the instructions for the hitch... view full answer...
