I'm just never satisfied,

I changed from cloth manual seats to electric leather which was no problem. But now I've gone and got some leather memory front seats, so apart from the longer securing bolts that have to get, which I can sort tomorrow. However the problem I have is the large multi-pin block is missing on the drivers side, but it is on the passengers side? The passenger seat works fine. But the drivers seat don't do a thing. Do I have to pull out all the interior and move the large multi-pin block over to the drivers side or am I missing something? It is a R.H.D ex-plod car, if that makes any difference. PLEASE HELP...
