My wiring was hacked up and it didn't (doesn't) match the manual. The wires were cut and I was able to match wire colors and use the manual to get it done. I was lucky they left wire on both ends when they cut em. I searched and couldn't find a better schematic for it.
You wouldn't even wanna see my wiring... Don't you have another 990 you can compare it with? Thought you had another one.
