I did that to my NPX controller to eliminate HDP problems that Alltrax advised another contributor was an occasional issue with Club Cars. Have had no further problem for 5 yrs.
Just to be clear, which wires am I splicing? Are you saying to eliminate the red wire from solenoid and run from blue (key) and green/white directly to controller? Excuse my ignorance.

Golfdog, or anyone? Can you explain exactly what wires I'm splicing?
I think I understand what you're saying, but don't want to do it wrong and fry something.

If You are going to by-pass the MCOR safety switch, the best way would be to just put the jumper back on the 2-pin connector at the MCOR.

That will keep the limit switch in the FNR working and prevent any possible spark when changing directions.

Make sure you put electrical tape to isolate the jumper from making contact with the chassis.

If You ever get another cable or controller, it would be easy to undo the change.

So, the key (blue) sends power to MCOR ms and green/white ms on FnR, looking at diagram. So, by jumping blue to green/white, I'm eliminating pedal activation of the controller, correct? I assume doing this won't cause any issues?

Doing this could get me moving, but I'd rather not leave it that way long term. I need to get a cable that works and disable the HPD.

I added a connection to the blue wire from the key switch directly to the controller so that it powers up the controller before the pedal microswitch powers up the solenoid ( red wire from solenoid to controller #1 small post disconnected.)

Ok, I thought that's what you were saying but wasn't exactly sure.
I jumped the 2 pin connecter at the MCOR like Sergio said, and now I'm rolling again. The solenoid engages when the key is turned ON and the controller powers up, so I need to be absolutely sure to turn key OFF when parked.
Thanks for ya'll's help. I'll start a new thread when a new gremlin appears LOL!

What you have done is bypass the pedal microswitch if you jumpered the other wire to the MCOR (blue one) the solenoid would only activate when you pressed the pedal.

The issue with activating the controller before the solenoid is that you could burn the precharge resistor.

Changing the controller setting to disable HPD is the best long term solution.

No doubt changing the setting is the way to go, but the power to the controller thru pin #1 is via the solenoid coil circuit not the power circuit so I don't think the resistor is an issue.
