Right just to dig this back up again, I spent an hour wiring 2 x 4 way relays, 2 x 5 way relays and a flasher unit together this morning. Then ripped out the broken DB10 and flasher unit then carefully soldered the new relay setup in. Went to test it and no flash

Spent 2 hours checking the wiring diagram in the technical manual compared to the diagram I used to wire the relays. After a tea and smoke break I happened to glance at the flasher unit's wiring diagram and realised it hadn't been earthed

DOH! Now the only thing I can't figure out is why I don't have a warning light on the dash anymore, The bulb is fine as I've tested it but still stumped! Never mind I'll have another in the morning see if I can't figure it out. I can change the back lights then for the L549's I have

Oh and Sorry Jay, due to my wiring problem I didn't manage to get the lenses off, will do so tomorrow and run them to the post office Monday mornin' ;)
