Need help with the Whelen SCM85 wiring (connectors)

[NFD-102]

I was wondering how to remove the amp connectors on the whelen SCM85. According to past posts I need to switch the positive and ground wires to hook up to the Whelen TACTLD1 Controller. I don't want to rip them or cut them so that I have to buy new ones. I just one to take them out and and switch the wires.
