i would have thought red would be live and and black earth so you could put a multimeter across them and get someone to switch the ignition on to see if you have power getting to the connector. if its not getting power then its prob the relay but i dont know which relay it is.

did you check both fuse boxes?? on in the engine bay and one behing the glove box.

hospital visit was very major. knee realignment surgery as my knee caps havnt fused so are in 2 pieces, the sit too high( not in the groove that they should track in) and the tendon that attaches to my shin bone is too far over so pulles my knee cap off to the side. it was almost a 2 hour operation. had my right knee done end of may and left knee done yesturday morning. was in 2 nights with my right knee but only in one night with my left knee. am back home now. think that must be a record

in a bit of pain now though
