Default navitas ezgo 91 marathon speed controller

Navitas firmware makes their 420amp controller work with series carts, so all you need to do is wire the cn1,2 and 3 correctly.

This is where i am stuck.

cn1 says key
cn2 says gnd
cn3 says throttle

What wires would these be on a 91 marathon?

they also state they are oem wires.
Of the controller i have 2 wires in grey sleeve ( black and white) from below the throttle switch ( iis this ground and throttle?) the other is from the micro switch above the throttle Blue wire (is this key?)

In traditional setups, pin one is "key powerup" (or pedal switch), this is Controller Enable. Pin 2 & 3 are the 2 wires from the throttle pot (black & white inside grey sleeve).

this worked! BUT after testing forward and reverse (wheels turned ) then the navitas controller gave a solid red light, i checked all wiring and could not find anything wrong....so now stuck again.
