Once you know the rules, just follow the wiring diagram.

And, if you do not have a diagram, take one from the thousands of manuals that exist.

Make a copy and get two highlighters. Once you have a circuit installed, highlight it as installed. Once you have check the circuit electrically, highlight it working.

It is not as bad as people think.

There is a guy on ebay that sells 20 feet of silicon jacketed 1/0 stranded cable for putting the battery in the trunk. works real well.

A test meter would be a good thing to get as well as a crimp tool and utility knife. The rest is toolbox stuff.

Worst case, ask here.
