Hi,
Few months ago I bought a Vectra C CDTi and it had a CK3100 but the screen was smashed, so a couple of days ago I purchased a new screen unfortunately it doesn't work, there are no beeps or display and I’m not sure what else it could be I’m just slightly more than confused.

My main question would be what is the usual place to hide the blue box and what fuse is it normally hooked onto?

Thanks
Graham
