Your '95 has a 4 wheel ABS (antilock braking system). RABS is the older rear wheel only antilock braking system. Please clarify what exactly you are seeing (or video it and post it)

Yo highmay05,
Welcome!

4WABS Overview; "...The 4-wheel anti-lock brake system (ABS) prevents wheel lockup by automatically modulating the brake pressure during an emergency stop. By not locking the wheels, the driver can improve steering control during hard braking and stop the vehicle in the shortest possible distance under most conditions. The ABS controls both front and rear brakes separately.

Malfunction of the Anti-Lock Brake System will cause the Anti-lock brake electronic control module to shut off or inhibit the system. However, normal power assisted braking remains.

Malfunctions are indicated by the amber ABS warning light inside the vehicle. The 4-wheel anti-lock brake system is self monitoring.
When the ignition switch is placed in the RUN position, the anti-lock brake electronic control module will perform a preliminary self check on the anti-lock electrical system indicated by a momentary illumination of the amber ABS warning light in the instrument cluster. During vehicle operation, including normal and anti-lock braking, the anti-lock brake electronic control module monitors all electrical anti-lock functions and some hydraulic operations. In most malfunctions of the anti-lock brake system, the amber ABS warning light will be illuminated. However, most malfunctions are recorded as a coded number in the anti-lock brake electronic control module memory and assist in pinpointing the component needing service.
If system is OK, Code 16 will be present.
.
Most concerns which occur to the anti-lock brake system will be stored as a coded number in the Keep-Alive Memory (KAM) of the anti-lock brake electronic control module. This means that once a code is stored, it will be retained by the anti-lock brake electronic control module even with the key in the OFF position. The codes can be retrieved by following the on-board diagnostic procedures.
The amber anti-lock warning light will come on as soon as the vehicle is turned on or started to verify bulb operation, and will go out after 2-3 seconds, provided everything is normal.

When ABS codes are read out, code 16 will be present if the system is OK. This code is similar to the EEC's code 111. It basically means that the 4-Wheel ABS Electronic Control Unit (ECU) is indicating that everything is functioning properly electrically. In

4WABS Self Test & Test Connector Diagram, Component Locations, DTCs, 93-96; "...The 4WABS TEST Connector is red; located at the left-hand side (driver's side) of the engine compartment and marked ANTI-LOCK TEST;

➡ Light Flash Technique 1. Note: If 12V test light is not available, the amber ABS warning light also flashes during this test. Locate test connector in the engine compartment and install 12V test light between Pins C and E.
2. With the ignition off, jumper Pin E to B. 3. Turn key to RUN position. 4. Remove jumper between Pins E and B after 5 seconds.
5. Count light flashes of test light or amber ABS warning light..." read more; miesk5 Note; for all Resistance tests, battery needs to be disconnected; remove Negative cable at battery
Manually Clearing Diagnostic Codes:
All diagnostic trouble codes must be output, all concerns corrected (anti-lock light off) and vehicle driven about 40 km/h (25 mph) before diagnostic trouble codes will be erased.
Note: Do not raise vehicle on hoist and accelerate to 40 km/h (25 mph) to simulate driving the vehicle. Erroneous sensor codes will be set.
Automatic Memory Erasing: A diagnostic trouble code will be automatically erased if no system concerns occur for 50 ignition cycles.

The front inlet valves should read 5-8 Ohms each; all other valves should read 3-6 Ohms each. Sensors should read 800-1400 Ohms across the pins, and more than 10K Ohms from the metal shell to either pin. The pump motor sensor should be 5-40 Ohms. The acceleration sensor is a group of switches which should be closed when the truck is stationary & level. When the sensor is tilted ~1" up in the rear, pins 2-3 should go open; when tilted ~1.5" up in the front, pins 1-3 should go open.

ASAP, find out if speed control recall work, if equipped was completed @ Recalls Look-up by VIN (Vehicle Identification Number); or @ Welcome to Ford Owner | Official Ford Owner Site; or ... have VIN ready. While there, see most Ford dealer maintenance/repairs done @ any dealership nation-wide.
"Summary: ON CERTAIN PICKUP TRUCKS, PASSENGER VEHICLES, SPORT UTILITY VEHICLES, AND MOTOR HOMES CHASSIS, THE SPEED CONTROL DEACTIVATION SWITCH MAY, UNDER CERTAIN CONDITIONS, LEAK INTERNALLY AND THEN OVERHEAT, SMOKE, OR BURN. THIS COULD RESULT IN AN UNDERHOOD FIRE."
See this guide by jowens1126 to confirm recall status @ 93 & 94-96 Cruise Control Recalls Repair
Note that the 93 recall is different than 94-96.
