What I cought from the RD07B wiring diagram:

The relais you call a preasure switch is according to my knowledge just a
cut relais; that's the reason why the wiring is done the way it is at the
@.

This relais is connected to three cables:
Blue/Yellow -> same signal from CDI unit as for the Front Ignition coil,
               switching through the Black/Red to Black/Blue connection in
the relais
Black/Red -> provides +12V, coming from the Engine Stop switch
Black/Blue -> connection to the fuel pump, provides power for the pump

I can't find any preasure depend switch at all for the fuel pump.
So from my point of view a time relais switching through the Black/Red to
Black/Blue connection located near the fuel cut relais makes the most
sense.

Am I wrong ?


Have fun,
JJ
