9 chance out of 10, your '98 Ranger doesn't have PATs. ('98 is transition year)

Therefore, you need a bunch of dash wiring:

1. Grab the module behind the passenger air bag out of the Explorer
2. Grab the transceiver around the ignition lock of the Explorer, and the ignition lock.
3. All the wiring that you can reach between the two
4. The wiring from the module to the firewall
5. The PATS wiring from the firewall to the engine connector.

Ideally, you have the keys (and door tumblers from the Explorer).

Note: The 3.0 transmission doesn't bolt up to the 4.0 SoHC; you will need the transmission out of the Explorer too.
