02 accord window roll up wiring

I need to locate and know which wires are for the window roll up.  I'm installing a window roll up module and can only obtain one wire at the driver side switch when I tested with a volt meter and hit the switch. RED / Blue for left front roll up.  As for the rest either it's positive all of the time or does nothing when I hit the switch.  I need the rest!!

I've exhausted all effort of trying to locate these wires.  Maybe there's a negative signal that the switch are throwing out or does the switch link to a relays that I need to located?  I've tried tracing the wires for all the switches but led to nowhere(at least not to the main driver side switches.   Any suggestion or help will be much appreciated.

thanks

I was avoiding to run the wires to each switch to save some time but I guess that's the only way.

thanks
