Disco 2 electric leather seats upgrade

I have fitted the seats as all the harness is there anyway but i cant seem to get the seats to operate without earthing the orange & purple wire on the red plug under the seat ,you hear the relay click on the seat when you do this?
a)Is there another relay or fuse thats not there ?
b)my car had manual seats originally is ther a connection in the harness to be made .

please help

needs a session on aotologic or nanocom . need to tell body control unit that electric seats are fitted so it can energise relay
been there done it
