Crusader to be exact,yep,that’s the one I’ve got but it’s a different relay,so are these interchangeable Jim?The part number you have given is Siroc.and the one fitted is Schrack.
Not sure, but I didn’t know what you meant by ‘and the supplied from model’ ?
If it was supplied under that part number then my guess is that it is a direct replacement, not seen any other type than the clear plastic ones TBH.
Are the terminals numbered the same? I would have expected a leaflet in the box if it was interchangable but with different connections.
