I got a pcm from junkyard same year and motor size now abs light keeps dinging,digging, anyone tell me why please

 

Is the part number the same (other than the 2-letter suffix)? Could be slightly different part numbers. Typically the last number changes.

If P/N's match, might just be a VIN mismatch between ABS and PCM.

 

There is no white part number sticker on junkyard pcm just stickers saying warranty void if removed, which I thought kinda strange,but I figured it was just reading codes from other truck so I'm gonna remove the abs fuse until I can take truck to dealer to have pcm flashed,I'm just afraid the truck might no crank no start again so I'm leary of driving it
