LR baggs LJKC 3 jacks for LGX unit

[saspp]

Hi there
My 2002 Godin Flat five X is equipped with the LKJC for LGX unit with 3 jacks one for magnetic pickups, one for piezo transductors and one mix.
I'd like to replace the tone pot by a pushpull Artec BCU and neither me nor my instrument craftman sees where to solder the battery ground on the LKJC.
has anyone has a LKJC diagram or tell me how to do this ?
Thank you so much in advance for your advices
