well for start, get a wiring diagram... find your already there wires for the 3.8 and either the exisiting connectors will work, or you may have to just change some of the wiring connectors..... for the fuel pump and electric fan, find a fuse on the fuse box that is for something your vehicle does not have or is non functional, and check with a multimeter to see if its only hot when the vehicle is on.... then all you gotta do is wire it in there and use the right size fuse.... a 10A fuse should cover both of those but i'm not positive, depends on how many amps the fan and the fuel pump require, they should have some sort of rating on them, if they dont give the amperage, the resistance and voltage is enough to figure out how many amps it should draw
