I sent chris a pm about this but I figured it would help others that are in similiar situation as me. I got a 2003 buick regal with a plx wb hardwired into the car. I also have a 99 regal that I just had blow up on me so I am going to put a cam in while rebuilding. I would like to get another wb and have it as an input in the tuner also so I can also tune the gf's 98 gs. is there any way I could get a second little green plug adapter that the pro has so I can just unplug and re plug between cars. Hope this makes sense and could help others in my similiar situation
