Josh, so how would I go about taking JUST my front and rear dumps (2 wires to tap into inside truck, that runs out back to valves) which are 3 prong rocker switches, and wiring it to ONE single momentary two prong?  OR wiring it to a 6 prong (but I would only be pushing it one way, to dump). SEE my post above to know exactly what im trying to accomplish.   Thanks

i miss read your post with what you want you are going to need two diodes ( a diode only allows curent to flow one way) you need to tap off of the two dump side of the switches so that you have two loose ends put your diodes in line making sure that you allowing the current flow towards the valves and then connect both wires to the same side of the switch and 12 v to the other side  ill draw another little pic and post it. you can use one bigger diode and connect both wires to one side of the diode and the other side of the diode to the switch.

i hop this helps just remember that if you put the diode  in backwards your going to dump everything at once with both dump switches and the pancake wont do any thing

Josh, two last questions.

What size diode(s) should I get, as the local radio shack sells about 8 different diodes.

And second, it's a bit of a PITA to get behind the switches in the console, but wouldn't tapping into the wires (both dumps) somewhere I can access the harness, be the same as running two new additional wires off the existing switches? I can tap both wires where it passes under the dash on it's way to the console. I was just going to tap then run two wires with diodes on each, to one side of the switch.... other side would be 12v.

THANKS!!!

i would use there 3amp diodes that should be fine,  if you want can double them up but ithink you should be fine your not going to be hold the pancake switch for very long.  as far as where to tap into your dump wire any where you want to grab if from will be fine i would just make sure that you really tape them up really good after so they cant touch each other. let us know how it all works out.
