I have a 03 ford/mazda b2300. I'm curious how easy or complicated it is swapping an older 2.3 lima into where the 2.3 duratec fits. Ik it'll fit but I'm not mechanically/electrically inclined enough to know if the stock components are able to just plug right in or if I'll have to swap or mess with the harness and all the other "needed comodidades" like ac etc.
