A lot lol, but seriously I drive a 04 Crown Vic and I know I need around 22 to 25 feet to make it from the battery to the trunk. The Caddy a lil longer so you will prob need more but its best to just measure before you start to buy wire.
are you sure you need 22-25 feet my car is longer than a crown vic and i only needded like 12-15 feet and i know my car is longer because my friend owns a grand marquis and i don't think he needs that much power wire.
your car the fleetwood is only like a 1.75 foot longer so there you go i would get like 18 feet which is the length of your car so you have length for the bends in the run. then a couple feet for the ground depends where you ground it

Yea, but I forgot I didnt run it down the same side as the battery I had to go through a hole already in the firewall then back down that same side. Plus, Im planning to run a seperate battery and its going to have to go all the way in the back of the trunk by the taillights. He may not need that much, but its always better to overshoot than not have enough.
