You can find the catch code for your PCM in a few places. You are looking for a combination of letters and numbers in bold. Older vehicles will have a 3 digit code while later vehicles have a 4 digit code. In most 2000 and newer vehicles it will be on small white sticker located in the driver’s door jam even with the dash. Older vehicles you will have to locate the PCM and read it off of either the connector at the front or the J3 cover at the back of the computer. The examples show this code to be U4P0.(See Picture Below)
