Up behind the glove box is your ECM. It has a socket that the chip plugs into. Disconnect the negative bat. cable and plug chip firmly into socket. Socket may have a cover over it depending on what previous owner did. Make sure chip is secure and reconnect bat. cable. Attempt to start truck and see what happens. Worst thing that will happen is a no start situation. Search on here for more detailed instructions.

1) What is the code on the chip? There should be a sticker with the calibration written on it.
2) What is the code on the PCM? The PCM is located behind the battery. On the side of the connector facing the engine is a sticker with all the calibration info and part numbers. Need the BIG 3 letter/1 number code. (ex. FOU1)
Get me that information and I'll let you know if that chip will work with your PCM. If it's not compatible, we can reflash that chip for you so it works with your vehicle.
Take care.
