			Hello,
i also want to install a lifepo batterie with dc/dc booster.
hope you can helb me.
How can I disconnect the engine battery from the system and connect the service battery instead? 
Is there a manual or wiring diagram available?
I found this wiring diagram online. 
Is it fundamentally correct or even possible in conjunction with the S-TTK?

booster connected after the relay.
Will the battery indicator still work afterwards?
Thank you very much!
Christoph
