Still a newbie when it comes to hydraulics, so sorry if this seems like a dumb question. I'm wanting to do a 3 switch setup in my 67 Impala. I want to do Front, Back, and pancake. I have a 2 pump, 4 battery setup. I only have 2 dump truck solenoids. How exactly would I wire everything up? And what gauge wire should I run? How many prongs do I need for switches? Thanks in advance!
