Not sure if I am explaining this clearly but is there a way to move these wires around or do I have to get a new harness? Or is there another approach?
Finding the correct one is probably easiest…but instead of moving, is it possible just to add?
Not knowing the actual pin-out pattern, check it out. There are unused wires in the harness for a generator–if no generator kit is installed. Something probably will match up and can be used for the choke. However, there is more to the story than that. The two extra wires added in 1958 are for the ignition switch kill circuit. It probably will be simplest to just get the correct internal harness and be done with it.
I’ve seen this problem before. You can’t just add a pin to either harness as they are sealed at both ends. If you look close you’ll see that the pin outs don’t match. One of your pins goes to a dead hole. Even if you reassign the pins you will still be missing one. The easiest thing to do is to replace the internal harness with a newer one. I like to swap the 1957 harnesses out to gain the extra pins for the magneto leads so that a remote kill switch can be added.
Of course, if you don’t care about absolutely original looks, you can always run another wire for the choke out of the motor somewhere else all by itself – add a connector in-line with it if you want a quick way of disconnecting to remove the motor from the boat, then have it follow the original fat cable to the solenoid box by joining them with zip-ties.
