I did notice that [7-3/4" x 5" x 2 1/2" (LxWxH)] and it is one of my concerns on the system. When comparing to others - Ron Francis Access 24/7 is 5-3/8" x 3-1/4" x 3-3/8" and Express kit is 4-3/4" x 7-1/2" x 3-3/8". The Access kit is much smaller footprint and the Express kit is very similar sized - but the RF kits have 1-1/8" more height to them. I think that might be more of an issue for grabbing knees or things depending on placement.
New to car wiring myself and with too much information out there - I keep talking myself in circles. I tell myself "When I get home I'll order the RF kit", but then I read a stack of forums on using relays to improve your systems and...."Hey, That CC kit sure sounds nicer now" and then I look at my bank account and do a bunch of nothing. :banghead:
