I"m replacing a tecumseh 5hp with a 6.5hp greyhound and I'm not sure where to hook up the wire that comes from the key ( the physical key that you have to turn on/off that is located on the steering wheel). Honestly I'm not even sure how it works since it's just one wire. Can anyone help?
Wiring up the ignition key

That wire goes to the coil, and when the key is turned off it shorts out the coil and kills spark.

I second the Kaptains post. You can connect into the wire going to your engines kill switch or the engines low oil sensor wire you'll find located right next to the kill switch.
I'd suggest you just leave your low oil sensor wire unplugged and connect your key switch to its wiring harness end. (not the sensor end) You can then just leave your engines kill switch all connected up as normal and you'll end up with 2 functioning kill switches.
Most guys with clone engines like yours leave their low oil sensor unplugged cause It'll shut your engine off every time you go around a fast corner because your oil sloshes over to one side and it thinks your out of oil.

Rehashing this question...
HF 5.5 has the red on/off switch, I disconnected the wire that attached to the ground
point and reattached it directly to the 1 wire keyed switch up by the steering wheel.
Which should effectively override the red switch. leave the red one off at all times and the key up front then kills the ground and the motor should run?
YET the key doesn't effect the operation of the motor in either direction YET
the little red on/off switch still works?
How do I troubleshoot and fix?
Thanx in advance

I'd leave the ground and plug-in wire to the engines original kill switch attached so you'd have the option of killing the engine from the back if your throttle ever stuck wide open while starting. (you might not have time to reach the steering wheel kill sw...)
Then run 2 wires up to your steering wheel kill switch:
One ran from the engines kill switch plug in connector to your steering wheel kill switch wire terminal.
And a second ground supply wire from a metal portion of your engine to the steering wheel kill switches housing to absolutely assure its getting a good ground input. (because your steering column bearings/bushings and tie rod ends may not always transfer a good ground input to this switch)
