The oil pressure sender on a 1999 Ford F-150 is located on the engine block, near the oil filter. However, the exact location can vary slightly depending on the engine (4.2L, 4.6L, or 5.4L). It's usually a small, threaded sensor with one or two wires connected to it.

To be absolutely certain, you should:

* Consult your owner's manual: This is the best resource for your specific vehicle. The diagrams should show the exact location.

Remember to be careful when working near hot engine parts and always disconnect the negative battery terminal before working on the electrical system.
