A catastrophic WTF

[You Wish]

Ok so long story short got my hands on a HD T-case from an 03 slammed my case in its place just a few bolts kept what I could. ( new case in junkyard bound wreck my case busted chain link slapping case) I never slowed down to see that the plugs on the encoder were different. So here I sit 2001 2500 Suburban 8.1 with a brand new ( built in november of 19 case and I cant shift it with encoder. I cant find the schematics on line for either truck, I have re-pined the new one plug harness(03) with the female connector from from old harness(01) up at the fender. No Joy.... I still have a 6 pin (01) that is replaced buy a 3 pin (03) I have no idea what, where, or how. I CANT FIND A DAMN THING ABOUT THIS. Please any help. I NEED SOME JOY!!!!!! Btw... Im full time RV well travel trailer and my tower is my burden.......

Nothing is easy anymore. It started going this way 24 model-years ago. Now we sit deep into the 21st Century, and things are only getting worse. That's par for the course.

 

You're going to have to get the original encoder back on there somehow, some way. If you can't make that work, you're going to have to rebuild and use your old t-case. GM set things up nicely ... for THEM.
