I have a turbo xs dual stage boost controller, and its missing the wiring harness/plug, is there a way to install it without the plug? the harness usually have 2 wires, and the boost controll has 3 terminals, how do I install this.

the website does not have instruction for this so dont tell me the website.
I dont have the plug.
thanks

 

im sure u can i don't see why not, u just wont have a switch in the carbin for i boost or a high boost option

 

I wanna know if I can wire the switch in, without the plug, but I dont know which 2 of the terminals to hook the ground and which on the switched power, it has 3 terminals but the harness usually has 2, I dont get it

 

got my. info man ya'll have know help when it comes to technical questions.
I called turbo xs and they said the middle post does serve a purpose. the left and right post can be used as a positive and negative, it does not matter which one is hooked to ground or switched 12 volt. for anyone else who may need to know
