67 Barracuda with 383 and ECU… alternative engine harness options?

In 67 there was only one harness, all engines, all options.
Al. Are you sure?
My '67 HD Barracuda was orignal a 225. The original harness has no tach wire.
The wires reached everything when I installed a 340, but the routing was not all factory so I wsan't sure if its the same or maybe not.
The only thing I know for sure was different was the tach wire.

The assembly drawing lists the following p/n for 1967 engine compartment cable assemblies.

I interpret that as 2 different main harness for the Barracuda and two different tach wires that maybe were wrapped into the main harness when optioned?
When you get a repop from Year One/M&H as I did, the tach option is already wrapped in (whether you want it or not).

Key:
C/ = 1967 models
B = Barracuda
0 = All
1 = six
2 = v-8
- L, H, P = cost level ?
