Rear steer joystick and control question?

Ok I took this off of a running unit and swapped it over to my buggy. Anybody know if this joystick is a self-centering unit from POS in which I read have went out of business? Any help will be greatly appreciated. I have searched the net and havnt found any info on this unit. It works awesome left to right steer wired the way the first guy set it up. I can say that there are 3 wires in each solenoid loom and the joystick has another terminal? Here are some photos.

not enough wires for self centering and you would have another unit on the rear axle

Perfect, Thanks for the info. Now I think I will just fab a centering gauge? Any ideas on this would help also.... Thanks Guys! First Buggy build so still learning as I go..
