i've been doing some searching over the net and i have finally found a decent picture the shows a pin out diagram similar to a p28.
i need to find the following:
-IG power
-Ground
-RPM signal
-Throttle signal
-Vtec solenoid
-Vtec oil pressure switch

so far i am able to find the following (but can anyone fill in the rest and confirm that theses are right)
-IG power (A25)
-Ground (A23)
-RPM signal
-Throttle signal
-Vtec solenoid (A4)
-Vtec oil pressure switch (D6)

can anyone confirm this and help me find the pinouts for RPM signal and throttle signal
