Magnum and Wiring Swap

I was never able to find much info. Seems like the color is right, but can't say for certain I ever even found a picture so could be I am just fabricating the memory.
Maybe we're both imagining it, who knows? I feel like I read about it a couple of years ago on an MS2/3 forum or one the that was Magnum motor specific on Tapatalk. And I'm pretty sure the Magnum forum got shut down because I can't find it. Maybe I'll search the interwebs and my bookmarks for it.
