Thanks alot for all your help mate
I've already ordered a 16 pin to 20 pin connector so should be here early next week
and as far as I know 7+8 are soldered together but if not ..... THEY WILL BE I didn't want to undo the cable but did try bridging pins 7 + 8 with a short piece of wire yesterday but it made no difference.
Pretty sure the i've followed the instructions right ....... It's not rocket science.... as they're very detailed but it's very time consuming!
Thanks again mate ......... Very much appreciated
