The first thing you want to check is that your truck has the harness connector under the hood. It is a wide flat connector with 8~10 wires just behind the windshield washer reservoir. If so, then it 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.
- Servo/module with mounting bracket and speed control cable (fits underhood where you found that connector).
Look for the parts from the same or similar year with the same engine you have.
IMPORTANT: To avoid the possibility of breaking the clockspring, you will need to verify that it is properly clocked to center before installing a used clockspring in your truck. This requires following the centering instructions printed on the C/S housing or in the shop manual.
