Thank you for purchasing the BT DieselWorks AutoSync. The AutoSync is a patent-pending revolutionary
new easy-to-install module that adds many enhanced functional and comfort features to many GM late
model vehicles. Please be sure to also follow the
quick-start guide
on the ‘AutoSync installation guides’
page on our website.
It is VERY important to register your AutoSync and pair it to your WiFi as soon as
possible to validate warranty and receive the latest firmware updates and new feature additions.
I know these instructions are long/boring, but
PLEASE
try to at least glance over every page
first. 95% of tech support email/questions we get are simply due to misunderstanding/not
reading the instructions.
NOTE: 2017+ vehicles have several feature limitations and also require one additional minor wiring
change under the dash at the Serial Data Gateway module connector.
Please see the additional 2017+
supplement document instructions on our website on how to perform this wiring change/pin swap.
NOTE: We now offer a plug-and-play SDGM bypass harness to make the installation extremely easy on
2017+ vehicles. This harness installs in less than 2 minutes and negates the need to do the old
wiring/pin swap. The wiring/pin swap can be tricky, and the pins are quite fragile…the SDGM harness
is less than $10 and will potentially save huge headaches:
