Sorted!!!!!
Traced the problem to the fuse box, at fuse 22 (10amp) for the instruments the connector that connects fuse 21 & 22 (-ve)underneath the fusebox was dodgy, removed the wires from the box altogether and re soldered them back into the loom in another place with another in line 10 amp fuse, so theoretically it's the same as before but completely bypassing the original setup.
