section B
is mby to ECU ?, problem is two identical connectors and they both cross-fit No, peel back the rubber and you will match wire colours. These go to oil pressure, water temp etc

section C
is to throttle Yes. Should be 5 wires in it.

section D :
have no idea,
five connectors (1)..(4) is 2-pin, (5) is 3-pin
+ one missing connector (6)
+ two "ring-eye", assume is goin' to earth Earth to IM. Grey ISV, Blue carbon canister control, black IM temp on IM. The other colour coded plugs all fit on the plug rail on the bulkhead.

Mine is any so might be minor differences

[Tractor Dave]

The three wires to the throttle body/IM should come from the same sleeve. All the multi colour coded tops should come from the big sleeve on the bulkhead.

Tapatalk isn't working so I can't upload any pics. I will try later

section E - Need more help ...
. "The other colour coded plugs all fit on the plug rail on the bulkhead."
. Yea, they fit but only two has corresponding color
.. mby "peel back rubber" and check wire-colors ?

[Tractor Dave]

This is ABY so yours might be different. This has also had Wagner IM fitted so couple of plugs extended to throttle body.

Section D
coolant temp (2)
distributor (4)
coil module (5)

I had a similar problem with wires and plugs when I bought my S2.
Just see where the wires naturally go. They are all the exact length for where they need to be and often find their own route back to where they were originally. Check also for Mark's on the sleeves as to where the retaining straps were fitted

Can't verify anything now, the car is in a garage 12km away ...

any thoughts on section E ? - connector color mismatch

Can't help anymore 're that as your colour plugs appear slightly different to ABY.
