Powerwise charger conversion for '74 36V Club Car

[laurent@gvtc.com]

I recently bought a 2004 EZGO cart that came with a 2004 EZGO Powerwise 36V battery charger 28115 g04. In 2015 I purchased a new Schauer 36V charger with a crow foot male connector for my 1974 Club Car. My goal is to keep the Schauer charger for my '04 EZGO and convert the 2004 Powerwise to be the charger to sell with my Club Car. The issue is that on the old 2004 Powerwise D-connector there is a smaller third red wire which I learned serves as a safety devise so that whilst the cart is being charged, it will not allow someone to operate the cart.
Is there a way to disable this feature so that I can use the Powerwise charger with a crow foot connector on the Club Car? I tried connecting the two larger black and white wires from the Powerwise to an adapter with Crow Foot connector plugged into the Club Car but the charger did nothing.

Thank you for your help.
