Hey guys I’m converting a 4x4 gmc to 2wd with a 80e. Is there a guide somewhere on how I need to set my trouble codes and other settings? Incase you were wondering why is because it’s hard to find rust free trucks in Michigan and I found my gmc which was very clean but 4x4. Front diff is super leaky, sloppy driveshaft going to diff, and so fourth. So instead of making a 4x4 turbo I’m just gonna go 2wd and set it up on some slicks and skinny’s.
Thanks for any help!
