Heater core delete

[cellkid22]

Hi all

I am in the process of building a spec boxster. I am pretty new to Porsches but fairly mechanical and think I am making good progress. Anyway I am looking to delete my heater core and was just going to put a bypass tube under the battery cover after removing the core itself but I was told I can do it at the water pump and eliminate a few unneeded lines running under the car? Can anyone shed some light on how this is done? Maybe a photo on where I can do the bypass?

Thanks
