Hi, New to the forum, I have followed this thread and have tried to get my speedometer working, (2001 3.0 ranger with 2000 mountaineer V8 swap) I connected a pin to my 4x2 ABS pin 19 , also connected a wire to pin 58 on the ecu, connected them both to pin 1 on the black cluster plug, (grey/black).
I still have no speedometer working, do I need the mountaineer ABS unit swapping in?
Thanks.
You should probably start your own thread for this
2001 Ranger used the OSS sensor on the transmission for the speed signal
The Computer(PCM) got the OSS signal, about 30,000ppm(pulses per mile) and then converted that to the 8,000ppm that the speedometer and cruise control needs, so in 2001 and up Rangers the speed signal came from the PCM
2001 Ranger won't have the speed conversion software in the ABS module
I think the simplest and easiest method would be to use a Dakota Digital SGI-100BT interface, about $115 now
It also allows for better calibration and tire size changes

You have already run the speed out wires, to PCM and cluster, so you just need the speed IN wires which can be accessed at the ABS module, the rear axle ABS sensor's 2 wires, pins 21 and 22 on 4WABS module
You may only need 1 wire, test the connector plugged in key off
Test OHMs to Ground, one should be 0 ohms and the other 1400 ohms or so, 0 ohms would be the ground of course so you should only need to tap the 1400 ohm wire to get the ABS rear axle sensor pulses
Ford uses the 8,000ppm AC signal so just 1 wire OUT, to PCM and speedo(and cruise), it only used the top(+) half of the AC sine wave for the pulses
Vehicle's ground completes the circuit
