Rear Window Defroster

[Thanatopsis]

I've been working on the design of a wiring harness to keep myself busy with coupe related projects while I save my pennies. I plan on it being a daily driver so I want climate control and the like which leads to my question. Has anyone installed a rear window defogger/defroster in a coupe?

I found this on the intarwebs: http://www.frostfighter.com/prt2600.htm
