right then, done
thanks to carl for all your help
here goes....
if you use the ecu harness connector terminal layout in the ecu troubleshooting guide, you can confirm the pin no.s which ill refer to below
code - pin no. - description - ecu wire colour - s-afr wire colour
# - 101 - injector signal - w/b - not applic on s-afr
I - 2 - rpm signal - l/b - brown on s-afr
P - 16 - pressure sensor airflow - orange - yellow (on wire going into ecu)
P - 16 - pressure sensor airflow - orange - white (on wire going from ecu)
T - 20 - throttle pos sensor - w - orange on s-afr
S - 32 - speed sensor - y/g - not applic on s-afr
U - 46 - 12v battery - w - not applic on s-afr
B - 47 - 12v ignition - orange - red on s-afr
E - 48 - ecu ground - b - black on s-afr
the orange wire for P is the one which you cut, the other wires are just spliced into.
hope this helps
