what i liked most, when you call them, they ask a lot of questions about everything you have and all you plan to have. you get a fuse box pre wired for all you need including any aftermarket stuff you would like to have in there. the one i ordered for the Vega was wired for electric fans, electric fuel pump, and they hooked me up with an extra wire off the headlight switch for accessory gauge lights. not to mention i got 4 ignition hots and 2 constant hots off the fuse box for future hook ups. they were very accommodating. i must admit though, the coolest thing is having every wire labeled every 6 inches directly on the wire. you can run it, and loom it up as you go to be nice and neat without worrying about keeping track of what wire is what cause its printed on the wire.
