Im installing a newer Johnson Heat exchanger pump on my Syclone. GM uses black and brown wires, Johnson as Brown and Blue. No indicators on the wiring. Which wire is ground and which is positive??

Just hook it up and dip the pump into a pail of water one outlet at a time to figure out what way it's pumping. If it's not the right way you want, reverse the wires. Don't let it run long without the pump in the water!

one of the wires should have a small white piece of plastic on it with a ground symbol on it.. that is the ground.

then this should be together right. i think its running and pumping, the coolant will settle then move around a little so i guess that is it cavetating it. i felt the pump feels like its running
