I'm proud to share that I finally got my buggy working!! Turns out the issue was the stock on/off switch after all. After removing that, I bridged the 2 cables that was connected to the switch. Now when I pull the throttle, the motor spins!!
I'm not done yet. For some reason, the motor is spinning BACKWARDS!! How come?? Could it be that the motor I got was meant to be mounted on one side of the buggy but I mounted it on the wrong side? ? Do motors come in clockwise/counter-clockwise versions? I'm soooo close. Anybody know how to get the motor to spin FORWARD??
Here are some photos I'd like to share.
1. For the motor mount, I ended up drilling 2 holes into the motor's bracket and bolted it to the frame of the buggy.

I used quite a lot of plastic wire ties to tidy up the cables.
I'm waiting for the key lock thing to complete the upgrade.
Hopefully the fix to get the motor spinning correctly is an easy one. I hate to have to order another motor and wait a few more days...
Again, thank you everyone for your feedback!!! I will post some videos to my YouTube channel as soon as I get it running right.
