12v acc/ignition power source in trunk?

Is there a 12v acc/ignition power source in trunk?

Pin17 going to the tcu/mulf, is that permanent or switched power?

Measured pin 17 today and it's a constant power source, so can't use that.

Any other suggestions?

If you have satellite radio and there is a fan connected, you can tap the powerline to the fan.

Fan's always getting 12v when the radio is on? Looking to tap in just for a "remote on" for the amp in my trunk. I've also heard that the CD Changer power will work, but have yet to get a straight answer on that.
Seems so simple to just get a 12v power line in the trunk when the car is on but these cars make it impossible.

I don't have satellite radio. I don't have a cd changer but will the wiring be there?

I'm not sure anyone in this forum knows if there is a switched 12v power source in the trunk that turns on with the radio.

It's been asked 100 times but no one has an answer ha, bummer.

If that wasn't the case, I wouldn't have suggested it. Fan power turns on when car is unlocked, and turns off approx. 10 minutes after you lock it.

Well the original thread topic is 12v ignition power source, which I have no problem finding, my question was for radio power like you just explained. I was just clarifying which question you were answering. Thank you, I will tap into the fan power.

Looks like there is no option other than to run a wire from the head unit.

Yea, the sattelite radio in my car has no fan. I'm going to try and find the antenna power and tap that.

I ended up tapping into the exhaust flap power supply right where the left tail light is, I unplugged this for the easier version of the "golf tee" mod. So far it has power when car is on, and not when car is off, we will see if it randomly turns off while driving....
