I have a 1990 f150 with a 4.9 Could I use a 3G alternator from autozone out of a 94f150 with a 4.9 and if so is it a direct bolt on and also how exactly do you change the wiring to make it work properly cause my truck has 2 plugs and the 3G only has one plug and one post to attach power to I'm guessing but where do you run all the wires and how is it done
