Default 2002 lb7 4wd conversion

Hey guys, I have a 2002 lb7 2wd swapped the driveline over from a 2001 duramax parts truck only issue is it didnít come with a cab so couldnít get the 4wd buttons or the dash harness. I pulled the 4wd portion of the dash harness from a 2002 a couple weekends ago, pulled it out pin by pin labeled everything and took pictures. Started putting the harness in got it all light up, everything is where it needs to be but still not going into 4wd and the little amber lights on the 4wd switch arenít lightning up, just wondering if anyone could help me out thankyou

These might help. It sounds like either the switch or TCSCM aren't getting power properly.

Two wrongs dont make a right, but three rights do make a left.

Reality is a matter of perspective.
