steering wheel / clockspring wiring diagram

[2015TahoePPV]

Does anyone have a wiring diagram for the 2015 PPV steering wheel/ clockspring circuit?

I put a leather wheel with buttons in my truck, the cruise still works, but I've lost my backlighting on the steering wheel. I wasn't expecting the radio buttons or the cluster function buttons to work, and they don't. I added an aftermarket stereo and an iDatlink Maestro decoder, and it doesn't work either.

I bought the harness doctor LIN bus wire and hooked it up, didn't help. The next suggested step was a new clockspring. The only clock springs that I can find online are for one "with" or "without" the heated steering wheel. I'm wondering why there isn't an option for one without the radio buttons.

Can someone share the diagram or circuit theory so I can understand how this will work before I spend more money?

thanks!

Thanks! I have been to that site dozens of times, but never went up one level to find the 'regular' Tahoe, just the PPV book. Thanks again!

Just an update. I changed the clockspring as was suggested, but that hasn't restored the lights to my cruise swith, and the RH cluster control buttons don't light either. So far I've added the Harness Dr. LIN bus circuit and an idatalink Maestro controller for my Alpine stereo. The Maestro comes with a dual sided adapter which intercepts the wires between the dash harness and the clockspring. I was hoping that the signal tap it took there would allow it to interpret the different resistances from the steering wheel buttons, but there's still something missing. I'm attaching pics of the different steering wheel plugs for color references.
