i am trying to do the big 3 upgrade

well i know how to do it but i was wonderning can i use stock ground points to do the big 3

also for the stock pos wire that runs down into the engine and under the engine that wire i cut from the stock termianls and i am trying to make that longer so i can connect it to my new termainals so its not so short

so where does the pos wire end at so i can run a new power wire or do i not need that power wire what does it do

i have a 2001 f150 so some of u with f150's plz help me out as in wat i should do with that wire or does it even power anything

 
5.4l

ok there is a wire that connects to the pos terminal well actually two one goes to the connection where the alt wire connects right on the firewall i am sure you get what i am saying

then there is another pos wire that comes off the terminal and goes below the egine and i traced it and it runs all the way back to the back of the truck well wats the point of that wire and how can i make it longer w/o running 20 ft of wire

 
because when i cut off the stock terminal they have on there the terminal extands like 4 inches to the battery terminal so when u take that off its 4 inches short and when connected very tight for the wire to be connected and no it doesnt run to the starter

 
well when i cut off the stock terminal ford has attatched to the wire its very short and not much room to connect it to the terminal i will take some pics later
