**E46 DYI: How to make Cigarette Charger turn ON/OFF with ACC**

Hi All,
I have got several useful tips and tricks from this forum. But for the Cigarette Charger always on issue I was not able to find any got fix. The one's I found were very dangerous hack-job driving both the cigarette charger and radio off of the 5Amp fuse. I set out to find a better solution without spending too much. Below is the solution I came up with. This solution maintains the two separate circuits for Radio and charger with their respective fuses.

Diclamer: I do not take any responsibility if you screw up and anything on your car is damaged. This tutorial merely documents the steps I followed to get the fix working on my 2005 E46. If your car is any other year I strongly recommend verifying the fuse board layout is similar to 2005 E46 before you proceed.


Things you will need.

1. Add a Circuit ATC Fuse-TAP

2. A donor fuse to to extract a spade connector
3. Digital Multimeter

Steps.
1. Remove the 5Amp fuse from position 7. Start the car and verify the Radio does not turn ON. Keep the Fuse Aside. Refer to the Fuse placement chart under the fuse board if the Radio turns on after you start the car.
2. Now remove the 20Amp fuse from position 47. Verify the cigarette charger does not work anymore. Keep this aside.
Refer to the Fuse placement chart under the fuse board if the cigarette charger still works.




3. Now place the 5Amp fuse in the bottom row of the fuse tap and the 20Amp fuse on the top row of the fuse tap. See pic below.


4. Now break the donor fuse to yield a connector as shown below


5. Trim the non spade end of the connector so that it can be inserted on the wire end of the fuse tap.Make sure it is set in firmly.

6. Using a set of pliers crimp the wire end to make the spade connector set in place. Pull the spade connector with some force and make sure the spade connector does not fall out or move too much.


7. Now place the fuse tap in position 7 and the wire with spade connector on the top end on position 47. *********Make sure you dont plug it in the lower end as that is always +12V ********* Doing so might damage the switching circuit when you start the car*******



8. Now start your car or put the key in ACC position and verify the Radio and the Charger turn ON. Turn your car off and the charger should turn of as well.

9. Now carefully tuck the wire in a good position and lock the fuse board back in place. Verify again by starting your car that it works and nothing was unplugged when you put the fuse board back in place.

You should be all set

Prashant

Worked, great, thanks!
Instead of using a disassembled fuse, I crimped a spade connector to the end of the wire coming off the fuse tap. Works like a charm.

Great idea, so much easier/cleaner than tapping into the radio power or running a new wire

Did mine today. I am very happy I finally don't have to remember to unplug my GPS!!

The "hardest" part of this easy MOD is to get the spade out of the donor fuse. @invisible_man: I don't see why I would buy a spade connector when I have so many spare fuses lying around. Besides, the spade connector won't necessarily connect any better to the fuse-TAP wire.

One uncertainty I had was the fuse-TAP also had a rating. I only saw 10 amp and 30 amp at my local Advance Auto Parts and I bought the 10 amp one. Not sure it matters if I only use it for GSP and cell phones.
