Got my new optima battery all mounted and ready just have a few things I want to clear up before I go any farther. The wiring going up to the front like the relay and the starter and all that, should that go inside the car like underneath the carpet and rails or should i go underneath the car like on the outside? Also does anyone have any clever ideas for an on/off switch that isn't totally ugly. I've seen some behind license plates then you just remove the plate at the track, I think that's what I'm going to do but just wanted some other ideas, pics would be great. THANKS!
