Yes, its quoite easy to remove the seat. look where the seat belts came from joint between the seat and back rest, there is a 10 mil screw which u need to take it out first in able to release the two clip under the seat. then it will be able to remove the seat easily. for the front engine, yes u can tidy up by putting all the cables into crimp tube...i did mine last weekend and run all the cables under the carpet..not an easy task, but looks more neat...
