Neutral Safety Switch

Forgive me for being ignorant. I learn by doing or seeing.
I would understand if you are getting frustrated.
So, 85 on the "starter relay" goes to the center pin on the NSS?
86 goes to the + side of the toggle switch?
Does the toggle still get grounded?
87goes direct to the starter solenoid on the starter?

I have tried a few scenarios and nothing has worked.

The way I have it wired without the NSS it will start and run but in all gears.

I only get frustrated when people don't read carefully, and follow thru on looking up diagrams on the internet for guidance.

Yes, 85 to NSS

86 to a terminal of "starter switch"
+12 V to other terminal of "starter switch"
There probably is no terminal marked "+" on the starter switch, but if there is, use it for 12 V.

No. Do not connect the starter switch to gnd. I clearly said that. It is now only on the high side.

Yes. 87 goes to the starter solenoid.
Before connecting it, attach a multimeter from 87 (red probe) to gnd (blk probe) and see if it gets 12 V when you press "start". Of course, must be in P or N and must have ignition switch on.

Theory. When you get 12 V across the relay's coil (85 to 86), you should hear it click and get 12 V thru (from 30 to 87).
