Next we have to remove the radio to expose the big open bay to mount the new cup holder. A few screws in the glove box should do the trick.
Pop off the plastic trim and we can see what we are up against…
Interesting… They are using the star pattern tamper proof screws but a standard socket also fits. Not sure what GM was thinking about here?
Finally pop out the radio and unplug the wire harness. Ohhhh nice big open bay. Not very deep though 🙁

Hi Shawn,
It does control the ignition. It was installed in the car when I purchased it though.

well…crap. guess ill have to figure it out on my own then. by the way, is that a sunfire? somebody saw the picture and said it was

found it. http://www.autotoys.com/x/cust/product.php?productid=317&cat=174&page=1

Yes it is a Sunfire. Nice find, that module seems interesting. I would have thought there was a controller box somewhere and that unit was just a matrixed keypad. By the look of the simple design it looks like someone could simply cut the keypad module out of the circuit and hot wire it.

perhaps, but if the keypad was recessed into the dash or wherever it was mounted, it would be diffucult. i think that it is probably more for the cool factor than security.

that’s fantastic but I am having a bit of trouble following your wiring (I’m not techno pro so forgive me).
Could you draw up a basic diagram (or anyone else) please?
I have the parts but am not sure about wiring it up! :S

Hi Scott,
This should help, here is the pin outs of the regulator that is needed for the 5 volts

Here is the pin out of the CD-ROM power cable.

Thanks, I’ll see how I go. Unfortunately I burnt out the button on my last DVD drive whilst trying to wire up another button to it. If I ever get it to work it will be pretty awesome.

I wired it up and it worked like a charm =) So happy.
However, the regulator was extremely hot after about 1 minute of being connected :/ Is this meant to happen? How can I fix this?
Thanks!!!

Depending on how much current the 5 volt control circuit draws it could get hot. Generally for more than 100mA of continuous draw you will need to operate with a heat sink. If the regulator you got is a to220 case style http://www.ges.cz/images/pictures/t/to220.jpg then you can get something like this to bolt onto it http://www.radioshack.com/product/index.jsp?parentPage=search&summary=summary&cp=&productId=2102857&accessories=accessories&kw=heat+sink&techSpecs=techSpecs¤tTab=summary&custRatings=custRatings&sr=1&features=features&origkw=heat+sink&support=support&tab=summary
The normal configuration of a LM7805 has the center pin and tab being common meaning you could also mount it to the metal of your car to sink the heat.

Awesome, thanks for the help! I have the day off tomorrow so I’ll give that a go. Hopefully I can get it all done in a day though I am doubtful!
I’m also going to have to borrow a solder sucker to rewire the button in a more convenient place.
My next project is a bush starter button that is wired in to the top of my gear shift knob. 🙂 That’ll be hot.
