matt3579 Posted January 31, 2017 Share Posted January 31, 2017 hey, so i have neons on the car already running on battery with a switch so i can turn them on and off. that all runs fine. i want to add a addition wire in there so they come on when the car is unlocked basically with the interior light but i understand this can cause issues with the bcm and i did try but kept blowing fuses except the 30amp one but the wires got hot quick so took off. is there another 12v source that i can tap into that becomes live when the car unlocked like the dome light? thanks Quote Link to comment Share on other sites More sharing options...
mattross1313 Posted January 31, 2017 Share Posted January 31, 2017 Not sure about a live on unlock, but I know some folks have tapped into the door switch so your lights could come on when a door is opened? Quote Link to comment Share on other sites More sharing options...
Jay Kay Posted January 31, 2017 Share Posted January 31, 2017 Surely you'd need a relay and/or switch live rather than overpowering the puny live for an interior light? 1 Quote Link to comment Share on other sites More sharing options...

Stan Posted January 31, 2017 Share Posted January 31, 2017 Relay will be needed for sure, you can't draw too much power through the existing wiring that is designed just to run a couple of interior bulbs, no wonder it keeps blowing 😉. Relays are simple enough to wire up, and you can tap into the direct feed you already have coming from the battery using thicker gauge cable that can handle the current draw. Then all you need is a negative and a wire going to the interior light wiring to switch the relay on. Quote Link to comment Share on other sites More sharing options...

Stan Posted February 1, 2017 Share Posted February 1, 2017 Any ideal what kind or relay would be needed ? Any basic 4 pin 12v relay, a 30amp one will be fine for running up to 360w of equipment (so hopefully your neons don't exceed that). They are about a fiver on ebay Quote Link to comment Share on other sites More sharing options...
