Power points for magazine wiring issue

Just got a blaster together i had broken down to upgrade…project was delayed and sat in pieces for a couple of months somehow the wires that send power to contacts inside of magwell for powered magazine were broken off and lost.so im trying to find a diagram or someone who can tell me where to run those wires from …the blaster is an Emerbu M4A1 with metal gearbox and gears …any help will be appreciated i am fairly new to performance upgrades

Googled it, appears to be a gen8 “scout”, basically a gen8 with select fire using v2 style trigger block.

This may help.
