hi I have a disco 1 200tdi which according to v5 was an automatic now manual its converted into a pickup
the wiring is a rats nest and I think I have activated the immobiliser as it wont start and electric windows do not work I really could do with a wiring diagram as Haynes is US and would like to eliminate the alarm/immobiliser. Headlights won't work but will flash main beam (new LED headlights)

Hello and welcome
best to ask over in the disco section of the forum
