Just buy the Canbus module from K8StingerStore that was just released. Cheaper than buying the OEM remote start.
K8SS Canbus Control Module
Yes, cheaper and a ton of functions like the turbo timer, but have you looked at the installation instructions for that thing? It should come with a dedicated support phone number.
Geeze, I was an installer and I’d have to set aside a few sober hours to knock that out. I could only imagine a DIYer. On the flip side the factory remote start is practically plug and play.
Wiring an aftermarket remote start would be easier and less time consuming, and most also have a turbo timer feature that can be enabled through the menu with no additional wiring.
