I have a very early working cabled one which I've used.
Only difference is the connector at the DI unit to aid easy swapping without having to hunt around the engine for 3 connectors.
When the very early originals failed, you got a new cableless DI and a cable set, then after just cableless di's.
Any red DI will fit any T5 ECU'd Car from 1988 to 1999, they just went through design changes cabled to non cabled, changeable ( individual) discharge unit to non changeable, probably different manufacturers etc.
