I purchased my 92 mazda extended cab from my cousin for 600 dollers,it runs great, has bags and lays frame.the truck is body dropped already,and has a sliding rag top.the fab is shotty on the frame,but the truck is worth saving.the air tanks have 4 nas magnet electric seliniods mounted to the 2 air distribution blocks.the blocks have 3 holes in bottem and 2 top,the top has 1 hole blocked off and 1 has the bags plunbed in to them,the bottem 3 holes have 1 hole open on each block,1 hole plugged on each block,and the last holes are plumbed in 2 the tanks.the seliniods are on the ends of the blocks.my question is how do i go from 2 swithces to 4 so that i can do not only front to back but also side 2 side,it is an old air ride kit.plu where can i down load some pdf"s contaning diagrams on these kits.   "thank u for youre help in this matter"  

unfortunately, if the truck only has 4 valves, you wont be able to hit sides. You have a front fill valve, a front dump valve, a back fill valve, and a back dump valve. The front valves tee off and supply both front bags with air and the back valves supply the rear bags with air. In order to hit sides you will need 4 more valves (8 valves total) to where each bag has it own fill and dump valve.
