Do you have the factory service manual? It should tell you everything in that.

Other than that, it's a bit hard to diagnose. Have you recently changed or removed the steering wheel? People often have issues with the steering angle sensor being misaligned.
What are the actual problems you're having?

yes it has an aftermarket steering wheel, i have tried to realign it but light still comes on, when going fast in a straight line, its all over the road.

Ah, defintely sounds like the steering angle sensor is misaligned. You need to take the boss kit off and put it back on with the wheels straight and the sensor aligned to centre/zero.

how close does it have to be?? at the moment its about 1/2 tooth on the spline out so i have to adjust the tie rods to get it centred but i thought that 1/2 a tooth wouldnt matter

Well, it should be on zero, but half a tooth doesn't sound like it would be an issue. Strange.

when the hicas light is NOT on the steering it real easy to turn but when the light comes on it gets harder to turn

True. When my motor was out, I removed everything. Front pump, lines to the back, rack, the lot. If you don't have the motor out, there are plenty of guides on SAU on how to remove the rear rack and loop the lines back on each other.
