I've done the 700R4 conversion on a couple of S8s and it's very straightforward and easy. It makes an amazing difference. They do require a small, gear reduction starter that is 12v. I converted my car (easy to do), but there is a place in Texas (I'll dig up the link later) that makes a solenoid for a 6/12 setup. There used to be 6/12 batteries made years ago (Orpin was the name of the switch/solenoid) but no longer. What it does is take two 6-volt batteries and runs them in parallel most of the time (6 volts). When you hit the start button the switch puts the batteries in series (12v) only to the starter and leaves 6 volts to the gauges and everything else. It charges like it's charging two 6-volt batteries. It's a slick setup that I've used for years. I use two Optima 6-volt batteries. With 12 volts to the (6v) starter it'll spin a V-12 over on a hundred degree day like it's nothing. They start so quickly it doesn't hurt the starter at all.
