Great, thanks so much for all the responses. All now working and sanity restored (well, partially anyway!) Replaced a fuse and the side door lock came to life as well (bonus!). Apologies for naivety, but am new to Bongo ownership so steep learning curve!!

Thanks again.

Thanks for the feed back guys. A techie guy at Cobra said that I need to break into a ignition feed that is also live whilst cranking and breaks when ignition is switched off. I connected to the feed checking with a volt meter showed live on cranking but apparently after a second call to Cobra it ...

I am fitting an immobiliser and the instructions are asking to break into a permanent ignition live. Can anyone tell me the correct colour on the dash fuse box to use please.

Also can you tell me what the round toggle switch with a red light is for to the right hand side of the steering column ...
