How do I connect this brushless controller square wave 12 pipe 48 /72,000 w to a key lock speed display twist Auto I have it all hooked up except for the little red wire and I don't know what to connect to the blue wire that is in the connector with the yellow wire that's on throttle connectors
 
How do I connect this to get my throttle to work I have everything hooked up all the plugins except for the one plug-in that has the yellow wire and it has a blue wire too and it's not connected to anything and where to connect the little red switch wire so I don't burn up the motor

The red switch wire should go to the battery through a switch in most cases. That's how you turn it on/off.
I would leave the yellow/blue alone until you can get the rest working.

I have a key lock display twist throttle hooked up to it and when I turn the key on it shows the volts and wheel starts spinning but the throttle dose not work
 
Wires marked alarm and key on these controllers usually go to battery voltage, but wheel should not spin immediately without power unless the controller as a learning mode.

Is this a new controller you just bought? Does the selling link show a description and wiring diagram?
 
Hard to tell exactly from the photo, but it looks like you ground and signal wires are reversed.
 
Picked it up like it said and I'll take I took it out of the house and laid out the floor so I'll take pictures out better turn the key on the wheel spins will you give it throttle and nothing even with the three speed switch hooked up it don't do nothingIMG_20250805_041455.jpg
 
How many conductors are there coming out of your motor? I don’t see the hall connector?

I added a longer wire on the hotwire or the negative
