Can you provide me with the harness link huge help thanks

Yes WAMS they Can program the Cluster for you For the steering coil: https://www.gmpartsdirect.com/oem-parts/gm-clock-spring-23381964

You can easily swap the Denali cluster Its a matter of programming and you can install the heated steering wheel but you have to change the steering coil for it to work But for the heated/cooling seats its not yet possible as in my knowledge

i dont have the pin 7 grey connector wire ( MOST control ) can you provide me with any assistance regarding this issue.
