Default Engine loom grey & brown plug pin out request

Hi all,

I’m looking for the pin out diagram for the grey and brown plugs on the engine loom, mainly for a 2002 wrx.

Can anyone point me in the right direction please?

cheers

Unfortunately the wiring diagrams do not include complete pin outs, only those connected to the individual systems that use each connector.

Relative section of Engine Electrical System (Engine Loom connectors are marked E* along with their mating Bulkhead loom connector B*)
E1/B20 being Light Gray; E3/B22 being Brown; E2/B21 being Black for turbo model.
See engine loom.pdf attached

The vacant pins on connector E1/B20 are used for AVCS cam position sensors on the STI model.
