I haven't seen many pictures of engine bays on here. I really need to see some becuase I'm getting ready to pull my 3.0 OHV and put a 4.0 SOHC in it's place. I need to know all the parts that I'll need to get from the 2008 Ranger with the 4.0. I'm going to post a pic of my 3.0 and a pic of the 4.0 SOHC. Take a close look at the firewall where the wiring harness plugs in. I only have one big plug and the 4.0 has 3 smaller plugs.
