Right well if everything works then i will just remove or leave it as i want the fusebox to be tidied so its easier to work on as when i unplugged everything and removed the engine the fusebox and wiring was a right old mess..

update on gearbox i have these part numbers
2 part numbers ive found,
o2A 945 413 B - on the shift tower - And google says this is the reverse light switch
o2A 301 107 C - on the inside of the housing - Quick google tells me its a 5speed trans housing
any ideas ?
Can get pics of gearbox if that helps people ?
