Be sure the disconnect can handle the amps your car will be using. 110 amps isn't a lot in todays accessory heavy cars. I would look into at least a 200 amp unit, preferably 250 if you have that kind of draw.... Electric fans, A/C, big stereo, power this, power that.. It all add up to a big demand. If the switch can't carry the load it will cause problems.

Thanks Mark for pointing that out about buying a disconnect that can handle enough amps, since I'll have Electric fans, A/C, big stereo, HID lights, etc.
