SCAG Tiger Cat II LED install

[Psu2ski33]

hi all- new to the forum here. Trying to install some LEDs on SCAG Tiger Cat II.I’ve got the LEDs and a harness that has a switch, relay and fuse on it. The harness switch does have a small red light to show “off” position. Worried this may drain battery over long periods of time and trying not to take that risk. Any way to integrate this harness into the ignition or Accessory outlet to ensure everything is off when the ignition key is off? Appreciate any thoughts or insights.
