CIS-E3 Fuel Distributor & cold start injector port

[ben swann]

Huw,

The picture helps a lot - looks like I got it right in the first place.

The engine and harness and entire CIS-E3 setup are from an 87.5 GT
coupe.  Everything fits great in the 4000 so far.

Regarding the harness wiring, I have been having difficulty determining
the harness connections - even though the Bently diagrams are somewhat
committed to memory, at least consulted frequently, the
changeover/differences in the harness wiring that interfaces with the
car is difficult to nail down - even some of the similar looking
connectors have wires in different pins or are different color/guage.
The wiring diagrams don't necessarily show things from a harness
perspective and connectors like T4f/2 doesn't tell me much even when I
look up location and type.

What I enquired about is what is not clear and perhaps someone has BTDT.

Ben
