Any ranger 04+ will have to be custom wired. 98-01 expo is usually the best to pull from.
That's false, My 04 was wired just the same as an 03, 4.0-5.0 4x4 swap. 07+ would be more realistic to say. Only custom wiring I had to do was on connector C139 which is below the master cylinder by the drivers side fender, which is for the battery harness. But from what iv read everyone that has done the same swap has had to rewire that connector.

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.
Keep in mind this was done on a 2000 model year, the wiring for that connector is the same on a 2000 harness as it was on my 04 model year (yes, I did use Ford EVTM's to check). Just a small example of how little the wiring changed.
Interesting. I see issues with how the Expo computer interacts with the newer instrument cluster...
nope no issues with communication. I was scared when I did the swap that the digital cluster wouldnt work. But come to find out that wasnt true either. The 04-06 cluster is wired a little differently than an 03- because it does have a built in microproccesor. But the way it communicates with the ECU works the same as with the analog gauges that were in the older rangers and expos.

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.
What are the possibilities of putting one of the digital clusters in a 98-03 then?
Well I tried to hook up an older analog cluster in my truck and that wasnt happening without rewiring the plugs. On my digital cluster there are 3 connectors that plug in, where as on the explorer cluster I had only had 2 connectors that plug in. I believe the big difference in wiring between an 03 and an 04 comes in the dash harness, considering the fuse box(smart box) on my 04 is on the passenger side. An 03 fuse box is located on the drivers side. Also the connectors for the clusters are also different. As far as everything else I have looked at it's all the same. In order for my speedometer to work I had to wire in a sensor that I heard someone else had tried on a sport trac 5.0 swap and it worked. I believe Bob mentioned it.
