You might want to consider buying a FSM, or a cheap knock off like this one:

Conversions contain alot of wiring and some diagram of some sorts is a must have. I remember I spent almost $80 on a factory wiring service manual from the dealer for my conversion..

..also if you have a local garage who you are pretty close buddies with, then maybe they wouldnt mind printing out the parts of the wiring diagrams that you need. Marlin's automotive service next door to the Crawler business has the Mitchell ondemand and Alldata systems and I was able to print out about half of the wiring I needed, but its not the same as the FSM. The FSM was all fully illustrated color pictures including color pictures of each and every plug with indications of each and every where. It was a true life safer.
