Thanks, calj737.
I'm out of 16 gauge RED, and in an effort to keep this all relatively clean and consistent, I will have to pick some up tomorrow. I'm excited to get this all wired up!
Koso Brown was soldered to some 16 gauge Black. I traced the Black lead on the key ignition harness to a 3-way connection point on the wiring harness and crimped a bullet connector on and plugged it into one of the open connections. Hope that's correct and alright to do.
Dark GREEN is the fuel gauge line which I can probably omit 'cos this and other 550s never had a fuel gauge connection to begin with, right?
I would LOVE to know if the Koso Gray line can be used to flash low oil or whatever. It'd be nice to squeeze out any remaining function from these mystery lines if they can be of any good use. Maybe I'll put a word into the peeps at Koso and see if they have any recommends. Keep y'all posted.
Meanwhile, I spent a little time extending the wire bundle on the stator harness to make it reach its new location under the seat.
Soldered extensions one by one so I wouldn't loose my place. A tedious process for sure but worth it if it all works in the end, as it should. See, with a little wrapping you could never tell it was extended.
I need to pick up some thick 4 gauge red and black wire long enough to reach between the battery and the solenoid. I guess there's an additional ground that goes from the solenoid to some mounting point between the frame and the engine too? Jeez, thinking back, I'm so glad to have scraped away some of the paint and powdercoat off of the engine and the frame while I still could; that'd be a nightmare to have to deal with at this point.
Feels like I made some solid wiring baby steps today. Thanks a lot for coming to the rescue, calj737. Thanks also to everyone else who's been chiming in to my meandering.
Ordered some of that Bel-Ray 20W-50 "mineral" oil. Due to arrive later this week or early the following week. Meanwhile, I hope to get all the crucial wiring done and instruments connected and powered up by/before the oil arrives. Can't wait to have my engine starting party. Been a long time coming.
