Our installation instructions are limited to the standalone related connections.

Over the years we’ve presented a ton of information here on this website, in videos, verbally over the phone and in printed instructions and supplements.

However GM makes calibration changes to each of their Electronic Modules internal software and hardware systems on an irregular basis.

In the end, it’s up to you the customer to check back here for updates to suggestions and installation techniques and make the appropriate modifications to your installation approach if needed.
