Well... the connector is gone. So I've traced the wires, there is Vs,Vc,Vb,THA,Ground...
I know it goes like fuel pump, ground, ground... then uhh... don't know how to order the Vc, Vs, Vb... already got the THA connected.
Can anyone tell me the pinouts from Left to right...
Cheers!

lookin at the air flow from left to right
i think its
e1 fc e2 vb vc vs tha
e1 in earth
fc triggers fuel pump relay or cuircut openin relay
e2 is sensor earth goes to ecu
vb this is power to airflow think its same power that powers ecu
vc is signal from airflow to ecu
vs is signal from airflow to ecu
tha is air temp signal to ecu

Cheers...
I got it all connected now... started her up. The injectors won't fire at all until I ground one of the two pressure switched... (any of the switch, didn't matter.) After grounding one of the pressure switch wires, the engine fired. Are there any reasons to this? (the ecu is running on a Volvo B20 now... and I don't have any pressure switches...)
Thanks.

Where are these pressure switches located?
#1 is to get more fuel when charging?
#2 is to cut the fuel whith max pressure?
#3 is for the knock computer?
Byt i can't find any switches.

They sit on a bracket near the brake booster on a TA63.
I was hoping these would be the problem on Boris' car but they seem to be installed/functioning fine...
