Morning all (Newbie here) - Looking for assistance on how/where there is an access point or usable grommet to run wiring for a dash cam back up battery (cellink neo 9) from main fuse box through firewall to interior of vehicle. I have all wiring and piggyback fuse holders etc and have identified which non essential fuses to use for the live and ignition on connections, but can’t quite figure out where to feed wires through to make necessary connections. Vehicle is a w639 Viano so same as the Vito.
Any help would be appreciated - thanks.
