I have a used box and was wondering what type or power it is all the writing is worn off. I do have a serial no. 24104 is there any way to trace it? Any help would be great Thanks

2003duramax,

No way to tell even if the writing was there it's all internal to the box unless the person who programmed it wrote it on the box itself etc.

Where the harness meets the plastic module, is there one or two multi pin plugs?

There is two where it plugs in to the box. Also can this one be reprogramed for a higher tune. I put it on the truck smooth power but not as strong as the edge/***.
