Found an "LS1" harness/computer on CL this morning but the seller kinda made it sound like he didnt know what he had. Id prefer one off an fbody, but his ad didnt make it clear, nor did his text replies. Are there any visible or measureable differences?

Seems like they are almost the same with the difference being the accessory locations.

The truck harness is upside down and backwards. The pcm is in a different location.
