In all probability, no. There are two harnesses required. One plugs into the back of the fuse panel in the left corner of the dashboard. This runs up the A pillar to the overhead console. There's another short one that connects to the computer. I don't have numbers for the newer trucks, but I did post some numbers for the '99. If you use the TDR search function using "overhead" or "console", you should be able to find them.
The way I found the numbers was to stick my head under the dash of a truck that had a computer, and got the number off the tag that was wrapped around the cable that I didn't have in my un-computered truck.
Remember, if you do any bombing, the computer may not give accurate MPG or DTE readings.
Your call!
