i just bought some 2 9" neon tubes to put under my seats and it says it connects to the 12v adaptor, but how do i install it clean without using the cigarette adaptor to connect them?

btw i only want these tubes to turn on when the doors open

 

Well youll have to tap into some other wiring preferably somewhere near where you will be mounting them. Check out this thread. Its for the ISPs, but the same wire they connect it too might be what your looking for.

 

thanks i will be wiring these either under the front two seats or underneath the dashboard
