will the lightning fuel pumps set up plug in to my stock 4.6 harness, also will the stock fuel tank work?

i know this is the wrong part of this forum to ask this question but i can not get a good answer on the exhaust forum are there any major differences i the cats on a lightning? will they bo too restrictive for the lightning engine? if so who makes a decent high flow cat, or what other cats will work?

any help is much appreciated
