I looked it up on the map-ecu website forum when they had it, it is pretty straight forward if I remember correctly. I did already have a plug-n-play harness for a SAFC 2 so most of the wires were already tapped into. I would recommend just getting a harness made, a lot less time consuming. Here is where I got my harness from http://www.boomslang.us/ they make good stuff. Let me know if there is anything I can help with.
