4.0 sohc wireing info
 

Im swapping over 2001 4.0sohc into a 99 ranger that came with a 4.0ohv.

My question is, Is this a plug and play swap on the firewall side?

meaning if i replace the engine wire harness should all the connections be the same or is the wiring under the dash different and i need to swap out dash wire harness as well?
