The stock harness wont take the added amps... you need to run a separate wire from the alt to the battery(you can run a relay on the alt wire if you want to have it shut it off so it isnt hot all the time) Add up all the amps that everything will draw and add 15% to it and thats what you need for a alt If you put the relays near the item/draw you wont get the line drop then you run a small wire to the relay from the switch
