Not exactly a wiring mod, but I would spend some time in calibrating the console gauges. As you get to driving your machine, you will probably find that -A- the water temp gauge lies, and -B- the oil pressure gauge lies. Both reduce your potential enjoyment of the car by making you worry. But if the gauges are calibrated, you'll KNOW they are lying. In the water temp gauge feed line, Ford engineering added one of three different resistors to bring the gauge temp down for 'owner peace of mind'. If it's there, it will simply be twisted into the single wire near the sender, then covered with electrical tape.
