If using a Road Rage (or a charge pump cicuit), you would simply use the standard wiring diagram. Ground is still "ground" or "0v", the effect is just running from 0 to -9V.
i will use a different dc adapter for the pedal, i know what does ground means, but, i i groung to +9v the input and out of the cables the could lead me a short, i mean in on edge of the cable will be +9v, and in the other side from another effect a -9v ground, this will mean that my cable will be in a short since the edges of the cable are the same... so im pretty sure that in the 3pdt wiring something has to change instead of just flip the -9v for the +9v in the ground of the switch...
im almost pretty sure that this its wrong
I usually use the diagram that's given in this build guide for the Rangemaster. There's a very detailed layout if you scroll through it if you just want the 3PDT layout.

thats basically the same, so i guess i will give a shot, i hope not to damage any of my pedals with this
Basically, ground is ground, 0V potential. The other lead from your DC-adapter is the "HOT" pol, and it can be +9, +12 or -9VDC (or something ...).
Which means, that you can chain any effects driven by (mentioned) +12, +9, -9 VDC, and ground them together as long as you have isolated DC-adapters (or batteries). Based on this i dont see any problems in wiring the 3pdt as you use to do, just dont forget to flip the LED in the correct way.
...hope i didnt say anything unclear...

its was clearer than water jejeje, i just try it uot and it work fine, i was just concerned about sending a positive voltage back to the guitar or amp, but i see nothing happens, and i see why the use of isolated powers supply fo this, thanks for clear everything to me.. you guys are awesome
