Some more wiring questions...
Circled is the bulkhead on the drivers side that connects the dash harness to the door, everything overhead, and the rear of the vehicle. There seems to be a lot more going on here than necessary. What is the best way to weed out what is not needed? For instance, from what I understand, the rear harness for the Ranger is under the cab on the frame. So this section of the Mountaineer harness would be redundant.
However, there are some functions of the Mountaineer that I would like to retain (power seats, power door locks, possibly power mirrors, but I don't want the power windows). The Ranger is manual everything and does not currently have any of these power functions.
And circled here is where the dash harness feeds through the firewall. It doesn't appear to meet the engine harness directly, but connects to another harness for everything else in the engine bay, including the fuse/relay box. This Mountaineer fuse box differs from the one in the Ranger, so I assume this 'third' harness will need to be swapped over as well?
Off topic, we've been having night time intruders stalking the neighborhood looking for unlocked cars. They help themselves to whatever they may find of value and move on to the next automobile. They could care less about being discreet, as they have been on video from several neighbors security cameras. Well, when I went out the other day the drivers door on the Mountaineer was open. Can't imagine what they thought when they saw the condition of the interior!
Thanks again for all of the great info!
