With respect to the CDI - the car currently has a special points-based distributor on it, which is the same kind as found on another Works car, and is potentially the same as an early L24 distributor, AFAIK. I've mapped out the entire wiring harness as shown below - this harness is in 2 parts (split at the fuse boxes) and has 2 Works part numbers, and date codes of 9/70 and 8/70, respectively. On the assumption that the wiring harness gets installed first, I've used this information to date the Works build as likely being 9/70 to 10/70, which would give the team about 45 days to test and ship the cars off to Monte Carlo.
This particular harness contains no additional wiring to accommodate a CDI, as would appear in a Z432 with CDI of the same era. That said, there has been some private discussion about whether a CDI was used via an alternate means, as there is evidence of it's use in similar period Works cars. In the case of my car, it's use would likely be facilitated via a separately wired harness, which is no longer with the car. As to an interface to the existing harness: there is a missing 6" sub harness at the steering column that has been replaced with a later-period custom harness. This could very easily have been the junction point where a CDI could have been connected, as much of the relevant wiring would be there. This is marked as "UNKNOWN" on the wiring diagram. It should be noted that this is just pure speculation at this point.
FYI, the above is my most current information, based on what I've already mapped out. It's entirely possible we may find more wiring surprises buried under the dash when we start the restoration process. Barring any revelations re: CDI, I'll likely restore it as-acquired, without it.
