Does any know where I can find the wiring diagram that includes the front wiper motor of a 2000 model 306 XT?

Seems to have 5 wires, but would like to know their functions.

In general, I've noticed a lack of schematic/wiring diagrams in this forum and on the internet in general. I havent even found maps of the relays or fuse boxes. Where do people normally get this info from? Is there a recommended book or other source?
