themlruts Posted December 22, 2015 Share Posted December 22, 2015 Guys I need to bring a hot 12v feed into the car. I will be running my firelights and a police scanner. Has anyone found a good way into the cab of the car? Its a lease so i dont want to go drilling if I dont have to. Thanks Mike Link to comment Share on other sites More sharing options...
securityguy Posted December 22, 2015 Share Posted December 22, 2015 Peel the carpet back from the passenger and drivers side and look for a rubber grommet with a wiring harness going through it. Typically, you can use a coat hanger to puncture the grommet or I actually have a fiberglass rod with a rounded tip that's specifically used for this purpose to push through and grab a hold of a wire you want to route from engine bay to interior. I haven't done this on a Legacy but this is your only option without drilling. Link to comment Share on other sites More sharing options...

GTEASER Posted December 22, 2015 Share Posted December 22, 2015 If you only need less than 10A, use and add-a-fuse on the interior fuse panel. Just find a circuit with constant power such as the interior illumination circuit or door locks and tap into that. This way you avoid going thru the firewall.

vtdog Posted November 9, 2018 Share Posted November 9, 2018 The scanner and emergency lights draw little power (unless you add searchlights). So, do the simple thing: buy a multi plug outlet for the 12v "cigarette" lighter connector and you can power your toys without a lot of effort.

ehsnils Posted November 9, 2018 Share Posted November 9, 2018 My solution is to have a slave battery in the trunk and charge it through the cigarette lighter outlet and an automatic separation relay that cuts the connection when the voltage falls below the charging level. There's a minute or two that there's back-feed from the secondary battery into the cigarette plug, but that's not causing any major trouble. I use that for ham radio operation.

capttris Posted November 10, 2018 Share Posted November 10, 2018 Why not just use the 12V Outlet? Link to comment Share on other sites More sharing options...
