First off is your alternator able to handle the second battery. If you are doing this to reduce headlight dimming this will make it worse. Second is the battery you are going to be using identicle to the old one. If it is you will not need an isolator if it is you will need an isolator. To install a battery without the need of an isolator you will need to run a high gauge wire(I would use a 2 gauge) from the alternator's positive terminal. Place a fuse that can handle the amps within 6 inches of bolth batteries( One next to the old and one next to the new) and then just ground the negative terminal(Make it the same gauge as the wire used for the positive cable). Take in mind this process should only be used with two i denticle batteriers, if they are not a battery isolator is needed. And you can pick up an insolator at your local car electronics shop or they can order it for you.

There really isn't much installing a second battery. Most probably you are installing a battery not identical to the original one in the vehicle. Whether the batteries are identical or not, adding an isolator just makes sure the two batteries don't "compete" against each other by draining off the one with more charge when your engine is not running (when your alternator is not charging). An isolator is just a high amp relay switch. Generally I've heard of (and myself used) a PAC200 isolator, which is a 200Amp relay. Just by looking at it, one can see 2 small connectors and 2 big connectors. The big ones connect the source or main battery's positive or the alternator's +ve to the extra battery's +ve. The relay (as any other relay), has 2 connectors, one of which connects to the ground(-ve) and the other to a +ve that is true ignition, meaning no voltage when the vehicle is not running. Maybe a simple picture will help.. Let me draw up one. and post it in a few minutes.
