Hi, I'm looking for the wiring for the steering wheel controls and warning chime to the radio. I installed an after market radio and cut the wiring to splice it in before I found out there was an adapter kit ( thanks Atoto and Amazon). It's for a 2008 2500HD.

Thanks in advance!

We used to have an online source but they stopped offering it.
Currently looking for an open source.
