This is not meant to be rude or smart aleck,but when I rewired my car I just bought 4 or 5 rolls of 14 ga. wire(to have different colors) one roll of black 10 gauge,one roll of red 10 gauge and a mess of connectors.Most everything on a car uses a 1/4 female spade.A handful of relays (you can get 30 and 45 amp relays from Advance for $4 a piece).I spent about $75-80,I think.I'm sure it was well under $100 for the whole car.Most expensive part of the whole job was new headlight/tail light pigtails.I just can't see spending $300-400+ for a roll of labeled wire.Not trying to make fun of anyone for using a ready-made kit,just figured might save someone some $$$
