v8 swap

OK, as far as I can tell without having the truck and engine here, this looks very straightforward. The 12 pin in the Ex harness matches up to the wires in a round 8-pin connector in the Ranger. I would either get the matching 12-pin connector from the Explorer engine bay or the 8-pin from the Ranger engine harness and splice it in to make the connectors match - it doesn't appear to matter which method is used.
All wires that need to be spliced have matching color codes. Obviously, this simplifies things. When finished, there should be connections of the red/yellow, grey/white, yellow/light blue, black/white and black.
For the yellow/light blue wires, the Explorer has one thick wire and the Ranger has 2 thinner ones to do the same job. All three would need to be spliced together. The rest are simply individual wire-to-wire splices.
According to the wiring diagrams, there may be 2 extra wires in the Ex harness that are unneeded. These are dark green/white and white/pink and they are for sensor inputs to the Message Center that the Ranger doesn't have. If the 12 pin has them, they can be cut off and insulated.
I think it goes without saying but the wires in these connectors live in a harsh environment that includes engine heat, vibration and road spray. Any spliced connections need to be of the highest quality. I prefer to use a soldered joint coated with dielectric grease and insulated with heatshrink tube and then protected by taped plastic convolute.

I have yet to get a hold of an EVTM to compare 07+ wiring to 04-06 wiring. From what I have heard the 07+ cluster communicates with the ECU over CAN network which wouldnt be compatible with an expo ECU, but then again you never know. Cant believe everything on the interent.

I am making a write up for it, but long story short anyone could wire in the sensor. Took me about 15 minutes.
