The first thing you want to check is that your truck has the speed control connector in the harness under the hood. It is a wide flat connector with 8~10 wires just behind the windshield washer reservoir and it may be covered by a plastic cap. If the connector is there, then your Ranger should be prewired for speed control.
The parts you need are:
- Speed control switch pods with wiring.
- Steering wheel trim that has cutouts for the pods.
- Speed control clockspring assembly (hidden under the column trim and wheel).
- Servo/module with mounting bracket and speed control cable (fits underhood where you should have found that flat connector).
IMPORTANT: To avoid the possibility of breaking a used clockspring, you will need to verify that it is properly "clocked" to center before installing it. The instructions may be printed on the C/S housing; if not, consult a shop manual. [A clockspring should never be sourced from a junkyard donor that has taken a hard hit to the front or one that has high miles. Unfortunately, a new clockspring is over $100.]
Another possible idea - Ford sold complete speed control kits for Rangers that were meant to be a dealer installed option. The original price was around $300+ but every once in a while a used one comes up on eBay for $100 or so. These are year and engine specific, so you need to know what you are buying.
