I did have electric RRC seats in a while back which were a bit of a nuisance to fit. I found the best way of fitting them and setting them in a nice position (I can't do electrics) was to tape the battery from a cordless drill to the cables.
I had to get rid of them in the end though as they gave me no leg room in the back, everyone had to sit sidesadle.
For some strange reason manual seats aren't quite so big.
Just thought I'd share
