90586, used on LHD cars to VIN 13349
91408, used on RHD cars apparently regardless of VIN
92991, used on LHD cars VIN 13350 up.
In addition, the GTs reportedly use a different wiring harness. I suppose that some very late cars may have had the GT harness, or some experimental predecessor thereof, installed during manufacture. But the Jensen factory was generally pretty good about changing part numbers when parts were revised, so one can reasonably expect all other JHs to have one of the harnesses listed above.
In addition to the Delta Motorsports wiring diagram, there are several others of which I'm aware. The Jensen Motors online version dated 1999, seems oriented towards European cars and lacks the special wiring used in North American vehicles. I don't have copies of the others, but IIRC they were all subtly different from each other, and at least one was both incomplete and wrong. For what it's worth, my car is a MkII with a 92991 harness, and before I removed the seat belt warning system wiring, there was a 100% correspondence between its wiring and Delta's diagram.
On the Delta Motorsports wiring diagram:
(1) There is a wire G-85-SC that runs from the IGN FUSE JUNC R.H. to a bullet receptacle labelled O/D FEED. This wire is powered when the ignition switch is in the RUN position. I would presume this to be the mystery wire in question.
(2) There is a wire WU-84-SC that runs from the IGN SW 5-WAY SOCKET to a bullet receptacle labelled RADIO. This wire is powered when the ignition switch is in the ACCESSORY or RUN positions.
