The tracing of wires is for another day but successful hunt through a few boxes...
....but less than successful attempt to share photos' here from Google account..... I will visit the old sheds and try again or shift them to Flickr !!
Two Looms - one unwrapped but labelled, if can untangle it looks OK/EU2, wrapped one I'm not sure about some of the plugs. Both need study and comparison.
5AS - Dated Week 48 1997 and YCW104540 complete with a sub loom of sorts with both plugs (also old tall immobiliser control unit on bulkhead next to the fusebox)
ECU - slightly smaller than the EU1 but same plug and a large raised X on the cover plate. Most identifiers illegible but a barcode on connector 19A1800180
Cream Injector set on a Fuel Rail
..and a Roadsport A Supersport 1.6 partially dressed
We'll ignore the 160 pistons on 1.6 rods (Oily's handiwork and minimal mileage), full stripped bagged and tagged 1.6, OEM Longbolts, most of a gasket set, sump pan, water rail, Elise TB, Vernier Pulleys etc.....
