2007Targa

20. 07 porsche 911 (Targa 4S). LoJack just lefty but unplugged the aftermarket Alpine updated head unit. I need to put the "Blade" into an unused fuse slot.

Believe I used C6 for a similar install. Works great.

Thank you for that, but it is occupied. Apparently I need to go into a vacant slot per the radio gurus...

Here's the fuse box diagram. I believe if you're only using the fuse tap for the accessory wire, using a currently occupied slot is not a problem. My understanding is the accessory line is only sending a turn on signal to the head unit. I could be wrong. Good luck.

You can tell just by looking in the slot. If the female blade receiver is only present on the hot side and the other side is empty, that gives you an unused slot. Them put your volt meter on DC 20V with the red wire on the present metal piece in the hot side of the fuse panel and the black on the metal catch where the door closes. Fond one that shows 0 Volts, then cycle the ignition to the accessory position and if you see 12v, you've found a winner.
