Is there a complete ECM wiring harness diagram hidden from my view?

Preferably from ecm to engine to c500? All inclusive?

Does anybody have a more readable version of the one online? I have the google doc. My apologies. I jumped the gun. Already had the doc it's just hard to read.

Does the fan switch connect to the ac relay? And c500?

Are these connections factory? Also is it OK to soak the wiring harness in warm water?

If you are going to be doing anything major with the electrical system, I would get a factory service manual. There are about 100 pages of electrical diagrams and good explanations on how the circuits are supposed to function.
