I have a Rocket-RC V2 LED program card. It didn't come with any cables. I'm trying to use it with a Rocket-RC 130A V2 ESC. I have a three wire JST style cable which almost works. It plugs into the program card as the top of the card has an (S + -) connection. The ESC (where the fan wire connects) only has two pins and it doesn't quite have enough space to fit the three wire cable as I was hoping.

Does anyone know where I can find the correct cable to connect these? Bummed it didn't come with the correct one. Tried to add photos but wasn't able to because my account is new.

Did you try and plug the cable that normal goes to the receiver into the LED program card itself, while also powering it with a battery?

Search youtube for a video called "Surpass Hobby V2 LED Brushless ESC Programming Card"

As Birdapi stated, you plug the ESC's receiver plug into it. That's the wire that goes from the ESC to the receiver.
