BMW MOD. SERIE 7 YEAR 03

POWER SUPPLY +30: connect directly to the big wire coming out of the battery terminal. It is suggested such connection

as some connections with fixed supply are deactivated by the electronic system of the vehicle after about

30 min. from the extinction of the switchboard.

STARTER +50: 2mm2 BLACK wire located in the wiring harness coming out of the MOTRONIC central

placed in the lower part of the antipollen filter, in the engine compartment.

Kola's absolutely right, in fact I would even ignore the ignition RED / green and RED / blue because we've seen some of these time out. Remember what I posted about that on your 6 series request. In fact, all the Germans, I would now suggest fuse box and/or battery.
