It depends on the year of the Ranger and the sub-model, if your sub-model, i.e. XL, XLT, STX, ect...., had an Option for something then a base wiring harness that had that option's wiring would have been installed at the factory, so it would be plug and play on final assembly......IF that option was added/installed
Like all Rangers were wired as Manual Transmissions until around 2001, and if an automatic was installed then a second harness was added that plugged into the clutch switch harness, by-passing it, on final assembly
The higher cost of having say 6 or 8 different harness's wasn't worth it vs the cost of the extra wires and just using maybe 2 or 3 base harness's
By 2002 most Rangers were automatics and most early options were now standard features
