Yamaha 704 Binnacle Control Micro-switch

I just purchased a new Yamaha 704 Binnacle Control that did not come with any instructions. The harness attached to the control has a small micro-switch in-line on one of the wires. What is this switch for and how does it get connected?

While I realize the 704 you purchased is the new design, have you taken a look at the old style 704 manual I have hosted?
If this does not help, can you share a photo?

You'll probably find that the switch is on in neutral. That
would be the neutral safety switch (so you can start in
gear and go flying when it catches). It goes in series
with the start switch. If you have a Yammy key switch it
should be plug and play.

Phil I sent you an email & pic.
Chuck, I too believe it's the neutral interlock. It's already a part of the harness inline on a brown wire. I believe it's a N/O switch but I haven't put a meter on it.

I don't recall seeing this part (highlighted) during my re-wire project.
Then again, you have the new version of the Yamaha 704 binnacle mount.
I would check inside my boat parked outside but it is tarped and there is a foot of snow on top.
If you need it, I can get to it this weekend.
The rigging guide (not for the engine) would show you all the hookups/wiring diagram.

The "micro-switch" is indeed the neutral safety switch. There will be a brown wire coming off both ends or the back from 2 terminals which will terminate in your round trim/tilt plug with 6 wires in it, red, blue, green, (2) browns, and a black.
Used to have to cut that plug in to wire in Zero-Effort Controls. I know that plug like the back of my eyelids!

Bob, can you tell me how to attach the switch? Please see the pictures. Inside of the binnacle control there are 2 cast dimple on the metal base and 2 molded dimples on the plastic pieces directly above the metal dimples. All four of these dimples appear as though they would snap into the four holes in the swith with the plastic 'arms' acting as a spring to retain the switches position.
What doesn't make sense is with the switch fastened in that position there is nothing that will make contact with the switch 'button' no batter what position I would put the control arm in. In other words, the switch would just sit there out of position for any mechanical contact to activate it.
Phil, please don't bother checking your boat. We'll get this figured out without you going to that trouble.

Maybe this address will work?

seahorse, on another site, sent me an enlarged picture of the inside of a control box. It gave me enough confidence to insert the switch where I thought it should go. It easily snapped right into place and there is no other position it would fit without intereference.
Now that it's in place I can see that a metal arm does swing and make contact with the switch button when the control arm is in the neutral position.
Notice that on the drawing, the switch is held in place with 2 screws whereas mine is held in place with a plastic retainer/spring device. This device also hides a little more of what is exposed on the drawing.
Thanks to all for there comments

CBO, Phil, now that I know more what I need to do I went back to the link you provide above for the instruction manual on the 704. That's an excellent document but I cannot enlarge it enough to be able to read it and even when printed it's very blury. I don't think it's my monitor because I have a high resolution Sony but - may be?

I got the photos from a CW member several years ago. Will send you the original photos via email.
Thanks for reminding me.
