Here it is!
Ok, I finally found the info after hours of searching and reading. http://forums.hybridz.org/showthread.php?t=82292&highlight=wiper+upgrade&page=9 is the link that will tell you how to do the install in post #177, on the previous page (page 8) in post #155, he has wiring diagrams to show you how to wire up the relay to fix the homing problem. I hope the thread helps cut some time down for anyone wading through all the posts looking for the right info.
