As most of you kn ow by now i have a complete pullout with ECm and all wiring from a 01 yukon that is drive by wire. I am looking to convert to drive by cable. now i did get all the peddles and small computer and all the cables for the drive by wire but was told i needed to use the drive by cable in my obs build.

Can anyone help with this. I have read many threads about this pcm and this pcm and all that but am still rather confused.
Thanks
