'05 30hp Mercury 4s EFI Fuse Blowing/Bad Engine Harness Help

[overthelimit]

Yesterday morning heading out for fishing turn the key and nothing, was thinking battery so tried backup and still nothing. Turns out the 20 amp main relay/accessories fuse was blown in the fuse holder assembly. Put a new fuse in and again as soon as I turned the key it blew again. 

Did a little snooping around today looking for a bad wire or something and found that the #6 receptacle on the Engine Harness Connection that connects with the remote control going to the ignition box is bad. It's completely burned out, I'm guessing this is where the problem is.

Does anybody know which wire would run into the #6 receptacle? I cant find anything in the service manual. I'm thinking purple? Looking for any input and possible fixes. Changing out the engine harness looks like a giant PITA and maybe a little beyond my realm of capabilities.
