Meth install - how to get 12v battery power in the trunk ?

tscdennab · 03-28-2011, 06:30 PM

Hi,

I need to get 12v power directly from the battery in the trunk for the meth pump (it is switched on/off via a relay). Is there a way to tap into the battery power lines ? Any threads on the forums showing how to do this in a non-invasive way on an e90 ?

Thanks !

Directly to the + terminal on the battery which is underneath the tray on the passenger side.

I ran mine from the cigarette lighter to the trunk from under the car.

He is running a relay and would require direct 12v and not a switched 12v so cigarettes lighter is useless
